INTRODUCTION

This document describes the commands understood by the rover software, in symbolic and numeric formats. The commands are built into sequences by the Rover Control Workstation (RCW) and uplinked to the rover via the lander. Telemetry packets generated during command execution are listed for those commands that generate them; these are described in detail in the Telemetry Dictionary (Mars Pathfinder Rover DFM 94-033). All other commands generate "Command Acknowledge" telemetry messages, if enabled by {CMD_ACK} or if the command is skipped due to an unmasked error condition. In addition, if any errors (at or above the current error severity reporting threshold {EREP_LEVEL}) are detected during execution of a command, an error report packet is generated.

Note that the RCW may define additional logical commands which are implemented as macros or aliases for one or more actual rover commands.

The sequence number is incremented (by the RCW) for each successive command, and is included in the secondary header of all telemetry data packets generated by the rover in response to that command.

Signed values are in 2's complement notation.

Commands marked with * are processed even if unmasked error flags are set.

Commands marked with (RL) are available in the the Rover Lite command set, possibly with some modification.

Eight error flags are defined (see the software design document for detailed descriptions). The following table indicates which commands can generate which errors. Specific error conditions are described with the individual commands.
