Goal:
Put every uplink sent to spacecraft as a new comment and post rationale for each packet sent.

Leader MTMSN 1

Invalid, sent before mission by accident.

pan state to manual
because belief that safehold could have a bug that causes the spacecraft to reboot every ~30 mins.
manual is basically safehold, but without fault response, but this is okay because what's currently faulted is the ADCS system, for which we don't want to activate any fault response until we better understand its failures.

downlink.toggle_id to 11,
in order to turn on gomspace boot cause flow

radio.max_wait to 10420 (approx 30 mins),
because want to limit quake power usage without limiting our transmission rate too much. we're rebooting every 38 mins anyway, longer durations likely don't mean much (previously we set this to 4 hours)

havt_disable18 disables the gyro heaters. This is a power-saving measure. This also assumes i2c comms with the ADCS is working. Noteworthy, if we see the havt disable later report heater as non functional, we know i2c is working with adcs.

adcs.state to 1 to ensure ADCS stays passive.

gomspace.piksi_off to turn off piksi as a power saving measure. It's not reliably reporting pos/vel anyway, and we don't need it during this checkout stage of the mission.

MTMSN 15

This is one more uplink of PowerSaving2 to the leader. The rational for each of the fields in this command remains the same as MTMSN 12,13, and 14.

We are sending one more of these uplinks as we saw a promising increase in voltage in the most recent downlink and we want to see if the trend remains.

PowerSaving3

This introduces two new power-saving measures:

radio.max_transceive to 10 cycles, to attempt to transceive 50 times less, to save power as radio usage
dcdc.disable_cmd to true, in order to ensure DCDCs are off if they are not already off

Modifications from PowerSaving2:

Remove command that sets pan.state to 11 (manual), keep it in safehold, this is because we don't think safehold is the root cause of the rebooting. Another reason to command safehold is that if the power-saving measures work very well, and the satellite never reboots again, it may also never transmit again due to the low max_transceive
Toggles attitude_estimator.ignore_sun_vectors to false to confirm application of commands.

Re-queuing PowerSaving3. Although the battery level observed on the previous downlink was low (6680), this may not be due to the power-saving measures but instead due to eclipse. We don't have enough data yet to see if the previous uplink reduced the bootcount rate.

Keeping the ignore_sun_vectors flag the same, since it seems that it was not set to false by the previous uplink. This implies that the MTMSN number that Quake reports in its downlink emails is not indicative of the last message received by the spacecraft.

Per our discussion earlier this evening, I am re-queuing PowerSaving3. The battery voltage increased to 7080 mV, and we agreed to continue queueing PowerSaving3 for as long as there is no apparent worsening of battery health over time.

No apparent change in rate of bootcounts over time.

The leader's vbatt has been oscillating between ~6700 and 7100. The boot count rate seems to have stayed the same

PowerSaving3 queued at 12:55am pacific time (two commands are now in the queue to account for the three hour gap in shift coverage), ignore sun vector set to false. This should have been true but was sent as false by accident, so we won't be able to tell from this flag whether this command has been applied.

PowerSaving3 + ADCS Power Cycle

We keep the two radio commands of power saving 3, as we know we've seen 2nd frames with power saving 3 settings. Thus, let's continue.

Keeping the gyro off is fine. We mainly want to see i2c reboot with ADCS, the gyro heater is not requisite for I2C functionality.

Keeping adcs.state 1 is fine because it keeps its actuators disabled. Does not prevent I2C functionality.

Keeping Piksi and DCDC's off is fine, not required for I2C, continued power saving.

Flipping Sun vector ignore as usual.

We stay in safehold just to maintain the reboot if no comms behavior

**We set gomspace.power_cycle_output4_cmd to true to reboot the ADCS.
Testing as shown that setting this field to true emulates ADCS going down, but also restores functionality a few seconds later.

    },

    }
]

The goal of this command was to force the satellite into Detumble, hence the pan.state and adcs.state fields. To verify if the ADCS bus is functional, the adcs_cmd.havt_disable9 command is set. Testing and analysis of flight code shows that faults are not updated as necessary and thus ADCS may appear faulted even when functional. Thus, the remaining fields suppress faults that would force the satellite into Safehold and would prevent Detumble.

The power saving commands from previous uplinks were removed in this more aggressive command in order to receive more downlinks. We noticed we were receiving more comms and even mag data without shifting flows. Since we believe ADCS may be functional, the power cycling command was also removed.

On 04/17/2022 on Sunday at 12:04 PM ET, sent a command to do 100ms prop firing out of valve 1.

04/17 approximately correlates to the above red, arrow, not enough of a disturbance in gyro rate was seen,

Seems safe to queue more prop firings.

On Thursday 04/21/22 at 3:25 PM sent another command for 500ms out of valve 1

Got one data point from previous command, does not look like large perturbation

Arrow points to the singular data point post last firing command

On Friday 04/22/22 at 12:47 PM ET sent two more commands (MTMSN 889, 890) for 500ms out of valve1

shihaocao · 2022-04-29T17:37:25Z

On Friday 04/29/22 at 1:36 PM sent 3 commands for 900ms out of valve 1 (2700ms total)
