- Telecom Report for SOLll
- 7/15/97, 15:52:00 PM PDT
-
- No new sequence was uploaded for SOLll. Only SOL10 commands were received.
-
- The Rover Telecom Subsystem performed nominally during operations for SOLll.
- The Rover radio modem and LMRE radio modem can be used without restriction
- for upcoming sequences.
-
- Statistics
-
- The Lander has been experiencing synch problems with the Block-V receiver,
- resulting in lost blocks in the downlink sessions. Attempts to verify APXS
- quality from Yogi were unsuccessful during the morning LGA downlink, at
- which point the analysis team was excused until further confirmation of
- APXS quality hopefully by late SOLll.
-
- Data on the LMRE modem continues to be patchy due to the lander's new
- strategy of disabling LMRE activity during IMP operation.
-
- Rover temperature dropped to -16 C prior to wakeup on SOLll.
- Peak temperatures reached +33 in the afternoon of SOL10.
-
- Lander side frame counts indicate a link quality of 85% for 549 frames.
-
- Rover link performance is down to 23% (2332 txmt for 543 rcvd) probably due
- to power cycling the LMRE modem.
-
- Recommendations for SOL12 are to continue heating the rover
- modem for 600 seconds, reheating 300 secs, prior to wakeup.
- LMRE power should also be switched to A-side (ie heating) for
- 600 seconds prior to rover wakeup, then back to B-side for normal
- operations.
