Back in November, I posted about the ESCAPADE Mars twin orbiter mission. I made a recording of the X-band telemetry with the Allen Telescope Array the day after launch, and I decoded the telemetry with GNU Radio. I made a preliminary analysis of the telemetry, showing that it contained a large number of log messages in ASCII. Shortly after writing this post, PistonMiner provided a deeper analysis of the telemetry, including a Github repository with some code and extracted data. She noticed that the CCSDS Space Packets, all of which belonged to the same APID 51, contained MAX simple telemetry frames in their payloads. Since MAX telemetry frames contain their own APIDs, this allowed separating the different types of telemetry data. Since seeing this, I wanted to go back and analyse again the telemetry to see what else I could find. Now I’ve finally had some time to do this. In this post I describe my new findings, as well as what PistonMiner originally discovered.
MAX telemetry frames
Recall that ESCAPADE transmits CCSDS TM Space Data Link frames carrying Space Packets in virtual channel 2. All the Space Packets use APID 51. PistonMiner realized that the payload of the Space Packets is formatted as MAX simple telemetry frames. MAX is the flight software of ASI, which was bought by Rocket Lab, which manufactured the ESCAPADE spacecraft buses, so this makes a lot of sense.
The structure of a MAX simple telemetry frame is as follows:
- Frame length (4 bytes). Since this frame format was originally designed to be carried inside a TCP stream, the frame length serves as frame delimitation. It contains the length of the MAX simple telemetry frame, excluding this frame length field. This is somewhat redundant when the frames are encapsulated in CCSDS Space Packets, since the Space Packets also have a length field.
- APID (2 bytes).
- Timestamp (6 bytes). This is divided into 4 bytes of integer seconds and 2 bytes of fractional seconds. According to the documentation, the fractional seconds count ticks of 1/40000 of a second rather than 1/65536 of a second, which would be more natural. The epoch for the timestamp is the UNIX epoch.
- Payload (N bytes).
The numeric fields use little endian ordering.
The following plot shows the values of the timestamps in the MAX frames that I have decoded, showing that the timestamps are correctly interpreted. Gaps in the data correspond either to missing data because the signal was too weak to be decoded or to a gap of almost 2 hours around 16:00 UTC produced by a technical issue with the recording. In this plot and others, the blue trace corresponds to ESCAPADE-Blue and the orange trace corresponds to ESCAPADE-Gold.
There are many MAX APIDs active. The following shows a timeline of the APIDs transmitted by each of the two spacecraft.
We can see a few interesting things in this plot. APID 520, which corresponds to log messages, is only transmitted sporadically, when a log message is generated. ESCAPADE-Gold is transmitting low rate telemetry after 16:00 UTC. We can see that the number of active APIDs is greatly reduced to accommodate the lower data rate. APID 740 is used to downlink files. This starts being used by ESCAPADE-Blue slightly before 19:00 UTC.
All the APIDs except 520 (log messaages) and 740 (file downlink) use packets of constant size. This makes it possible to plot a raster map of the APID data to identify telemetry fields. Here are a couple examples of these raster maps. The Jupyter notebook contains maps for both spacecraft and all their fixed-length APIDs.
APID 520: log messages
APID 520 contains asynchronous log messages. The payload of the MAX frames is the log message in ASCII. The following shows all the log messages for ESCAPADE-Blue, together with the timestamp in the corresponding MAX frame.

APIDs 620, 621, 622 and 623 contain some ASCII strings. The raster maps of these APIDs look like the following. The blue sections are ASCII strings (in this case, ConfigureRadioInternal, ConfigureRadioInternal, and WAIT_UNTIL).
APID 620 contains the strings CommsFallback, CommsFallback, EXPR.
APID 621 contains the strings DisableComponents, DisableComponents, EXPR initially, and later on first BackorbList, BackorbList, and WAIT and then BackorbDownload, BackorbDownload, and WAIT in ESCAPADE-Blue and LaunchSequence, one of DisableComponents, EnableComponents and SetThermostatMode, and WAIT in ESCAPADE-Gold.
APID 623 contains the strings FWReset, FWReset, WAIT, and is only active in ESCAPADE-Gold.
My guess is that these APIDs indicate the status of some tasks that are currently running, and they have string fields to list the name and state of task.
APID 730, which is only active in ESCAPADE-Blue, contains a file path in ASCII, followed by some numeric data. The raster map is shown here.
The file paths are the same files that are being downlinked in APID 740, so I guess that this APID indicates the file that is currently being handled by the file transfer service, or something similar.
APID 740: file downlink
APID 740 is used to downlink files. PistonMiner indicated some similarities to the CFileDownloadMgr data structures in MAX, and reverse engineered the format of these packets. I have also reverse engineered this independently.
There are two packet types: file declaration and file chunk. A file declaration packet has the following little endian fields:
- Packet type (4 bytes). A value of 0 indicates file declaration packet type.
- Identifier (4 bytes). The value of this field serves as an identifier for the file being transmitted.
- File size (4 bytes). Total file size in bytes.
- Number of chunks (4 bytes). Number of chunks in which the file will be transmitted.
- CRC (4 bytes). CRC-32 of the file.
- File path. A string that indicates that path of the file. It is zero padded at the end.
A file chunk packet has the following little endian fields.
- Packet type (4 bytes). A value of 1 indicates file chunk packet type.
- Identifier (4 bytes). The value of this field serves as an identifier for the file being transmitted.
- Chunk sequence number (4 bytes). The sequence number of this file chunk.
- Chunk offset (4 bytes). This field indicates the offset in bytes within the file corresponding to this chunk.
- Chunk length (4 bytes). This indicates the length of the chunk. It seems that all chunks are 1062 bytes long except the last one.
- File chunk data (N bytes).
I have implemented some code to reassemble the files transmitted in this APID and check their CRC against the corresponding file declaration. This is the beginning of the log that my code produces.

Since all the files are compressed with gzip, my code also decompresses these files. To preserve the original path of the file in the filename, I replace the / characters in the path by + characters. These are the files that I have successfully received and their sizes in bytes as reported by du -b.

PistonMiner indicates that “The .mtc files themselves look like they’re stored telemetry in the same format as the downlink but without the space packet framing.”. I haven’t looked into the contents of these files yet.
The BackorbDownload file is interestingly a FlightJAS script that commands the download of all these files (plus others that were downlinked after I stopped the recording). This is the script in question.

In the logs in APID 520 we can see how this script is generated on the fly by running commands on board to process a file listing produced by flight software. For instance, this is what generates the section for inv_cdh_spoc_misc files.

It makes sense that the FlightJAS script is downloaded as part of the file download sequence just in case it is needed for debugging (plus it also provides a list of all the files that are expected, since it is downloaded first).
APIDs 6084 and 6423: quaternion data
There are two APIDs in which I have been able to find unit quaternions in float32 format. The first of them is APID 6084. The raster map of this APID for ESCAPADE-Blue is shown here. It is apparent that the beginning of these packets is formed by 3 float64’s followed by 4 float32’s.
The first float64 corresponds to an absolute timestamp with respect to the UNIX epoch. The values are close to the timestamps in the MAX simple telemetry packet headers. In ESCAPADE-Gold, this APID has all zeros before around 13:00 UTC, so the timestamps and the rest of the data are invalid during this time.
The following shows the timestamp difference between the MAX packet timestamps and the timestamps in the payload for ESCAPADE-Blue. We can see that there are two events when the difference grows to up to 140 seconds. This happens because the data in this APID is frozen and doesn’t update during these events, while the MAX timestamps continue updating.
A different scale in this plot shows us that the timestamp difference is generally around 0.5 seconds, but there is a jitter of around 1 second. This basically corresponds to the latency from the moment the data on this APID is generated to the moment when it is encapsulated into a telemetry packet.
The next two float64 fields contain relative timestamps. They probably count time since the spacecraft was booted after separation. On 2025-11-14 15:00:00 UTC, the time since launch was 65099 seconds, while these timestamps show a value around 63000 seconds.
The plot of the difference between these two timestamps and the absolute timestamps is interesting. We see that there is a drift, and one of the timestamps has much less jitter than the other one. Also, the timestamps have a difference of around 0.8 seconds.
The four float32 fields are unit quaternions. The following plot shows the data for ESCAPADE-Blue in the first panel and for ESCAPADE-Gold in the second panel. Note that the ESCAPADE-Gold data is all zero initially.
There are several different conventions and formats in which quaternions can be used to represent spacecraft attitude. I have found that the most common convention is that the four-element vector uses scalar-last representation, and that the quaternion \(q(t)\) indicates the rotation from the spacecraft body frame to the ICRF frame at time \(t\). When reverse-engineering quaternions in telemetry, this assumption needs to be checked by making sure that when interpreting the quaternions in this way, they make sense.
The first thing I do is to compute \(h(t) = q(t)^{-1} q(t_0)\), which under this assumption corresponds to the relative rotation from the spacecraft body frame at time \(t_0\) to the spacecraft body frame at time \(t\). Usually a spacecraft rotates about a constant body axis at a constant angular rate, and we can see that in \(h(t)\). The following plot shows the axis of rotation of \(h(t)\) for ESCAPADE-Blue and ESCAPADE-Gold. We see that the axis is constant, and the two spacecraft have very similar axes, but with opposite sign.
The following plot shows the rotation angle of \(h(t)\). We see that the angular rate is constant, and ESCAPADE-Gold has a higher rate.
This is confirmed by the following plot of angular rate.
APID 6423 also contains quaternion data. Here is the raster map of this APID for ESCAPADE-Blue. The first 3 fields are float32 that contain gyroscope data, as we will see. We can also see the four float32 corresponding to quaternions in bytes 32-48.
The following plot shows the raw value of the float32 gyroscope fields. We will interpret this in the context of quaternions below.
The next plot shows the quaternions. The first thing we notice is that they are completely different from those in APID 6084. We will study them in the same way.
The next plot shows the rotation axis of \(h(t)\). We see that the axis is constant over time, and it is very similar for both spacecraft.
In the rotation angle of \(h(t)\) we can see that the angular rate is constant. However we already can see that the angular rate is different from the one we saw in APID 6084. This strongly suggests that the quaternions in the two APIDs are representing different things. The difference in angular rate cannot be attributed to a different representation only.
The plot of the angular rate confirms this difference. While for ESCAPADE-Gold the angular rate is around 60 deg/hour in both APIDs (but still noticeably different), for ESCAPADE-Blue the rate is around 45 deg/hour in this APID and around 20 deg/hour in APID 6084.
To compare the quaternions with the gyroscope data, I scale the axis of rotation in body coordinates vector with the total rotation rate to get the rotation rate in each body axis. This is shown in the left column of the plot below. I compare this to the gyroscope data, which is in the right column. For some reason I need to multiply the gyroscope raw values by \(-1/2\) to get a match. It is quite reasonably that we need to have a minus sign here, because I haven’t been keeping track of the sign of rotations very well. However I don’t know the justification for the factor \(1/2\). The gyroscope data is noisier and has a slight bias, but we get a good match.
This comparison is strong evidence that the quaternions in APID 6423 give the rotation from body axis to ICRF (or other inertial frame) in scalar last format. I have no idea what the quaternions in APID 6084 represent, given that their rotation rate is completely different for ESCAPADE-Blue. Perhaps they indicate some kind of target or predicted attitude that the spacecraft were not tracking at that time.
Something else I typically do when I find spacecraft attitude quaternions is to compute the line-of-sight unit vector between the spacecraft and the receiver in body coordinates. This can be cross-referenced with the received signal power to check where the transmit antenna is located in the body frame. For spacecraft that have SPICE kernels publicly available, the attitude kernels usually have a description of how the body frame is defined and where the antennas are placed.
In the case of ESCAPADE, the best I have found is this diagram. The high gain antenna is in the +Z face, and the two medium gain antennas are both in the +Z face, slightly tilted towards +Y. There are four low gain atennas according to the diagram. Two of them are in the +Z face, just below the medium gain antennas. The other two are not visible in the diagram. It would make sense to place them in the -Z face to have full coverage regardless of the attitude.
In the following plot, the X, Y, Z axes are shown in blue, orange and green respectively. In the waterfalls from the previous post we see that ESCAPADE-Blue’s signal is very weak until 15:00, when an antenna change happens. Then it is very strong at 15:00, and it is somewhat weaker and relatively constant at 17:00 and later. Part of the decrease in received power is caused by the increase in distance.
Assuming that the quaternions body frame is the same as the the frame in the diagram above, we see that at 15:00 the -Z axis is almost pointing towards Earth. Therefore, it sounds reasonable that the antenna change was from the +Z axis to the -Z axis. After this, the -Z axis antenna continues being used, and we get reasonable signal strength throughout the rest of the recording, even though the off-boresight angle is around 90 degrees between 18:00 and 19:00. This is somewhat surprising. I would expect poorer signal at 90 degree off-boresight angle.
In the case of ESCAPADE-Gold, the signal is quite weak around 13:00, then it fades in smoothly, increasing to a maximum. Then there is an antenna change and the signal becomes very weak. After 17:00, ESCAPADE-Gold is transmitting low rate telemetry, so we don’t get any attitude data.
Assuming that the transmit antenna is aligned with one of the spacecraft faces, the only reasonable choice is that the antenna used between 13:00 and 14:30 is in the +Z axis. This explains why the signal power grows over time. It does not explain why the signal is rather weak around 13:00, since the off-boresight angle is not that bad (it is around 80 deg). Maybe the antenna that was used was the medium gain antenna. At 14:30, it looks like a swicth to the -Z axis antenna happens, explaining why the signal becomes very weak.
So it looks like we can make sense of the attitude quaternions in combination with the received signal power and the spacecraft diagram. I am not fully confident about the correctness of this, since we don’t have enough data (it is easier to do this check when the spacecraft rotates faster and we can observe the effects of at least one full revolution) and because we have somewhat inconsistent results between the two spacecraft for off-boresight angles around 80 to 90 deg (although this could be explained by the difference between the LGA and the MGA).
Code and data
I have updated the Jupyter notebook to include all the calculations and plots used in this post. I have also added the downlinked files to the repository.
