The end-of-sol communication system performance for the downlink was as follows:
For rover wakeups on solar power, modem heating is only needed if communications is needed in the morning. In this situation set modem heating to 0 and reheat to 300 seconds. Also, if there are afternoon only downlink sessions, then no modem heating is required after wakeup on solar. The rover modem should be commanded in the next-day runout sequence to perform a 300 second modem reheat at wakeup. Later in the day, modem reheating should be triggered by an excessive number of frame retries on the rover-to-lander link, and the reheating should continue for five minutes or until the rover modem reaches +30 C. However, if the LMRE radio is off, then the reheat to get to +30C is not needed. This requires some coordination of timing between the LMRE ON times and the rover transmissions. The sequence planners should consider the uncertainty in event completion times introduced by any required modem reheating cycles.
