1. OVERVIEW

Packet formats are designed to allow high-level routing and grouping of data without detailed packet parsing or external knowledge. Packet data uses fixed formats to allow extracting data when some packets from a message are missing, or when the contents of packets are partially garbled.

Messages contain sufficient data, along with knowledge of the associated commands, for interpreting command results. In particular, data from other telemetry messages should not be needed (since they may be routed differently). Data from the command is not duplicated unless it may have been overridden by the rover.

1.1 Headers

Data types:
	U8	unsigned 8-bit
	I8	signed (integer) 8-bit
	U16	unsigned 16-bit
	I16	signed 16-bit
	U32	unsigned 32-bit
	I32	signed 32-bit


All packets start with:

CCSDS primary header (6 bytes):
	U8		08 (constant flags)
	U8		APID
	U16		packet sequence number + grouping flags
	U16		data length

• APID: used for routing packets
• Packet sequence number: consistent with CCSDS format, there is a separate packet sequence number for each APID. The packet sequence number starts at zero and is incremented with each packet sent for the duration of the mission, with rollover if necessary.
• Grouping flags: always 11 (no segmentation)
• Data length: (number of bytes-1) for rest of packet after primary header

CCSDS/MESUR secondary header (9 bytes):
	U32		CCSDS coarse time (seconds since 1/1/58)
	U8		CCSDS fine time
	U16		message packet number
	U16		command sequence number

• Time: time when packet was formatted for output, probably later than the time of data collection. Normal rover software sets the fine time byte to zero; rover lite sets it to one.
• Message packet number: number of packet within message (starting at 0 for each message); most significant bit is set to 1 for last (or only) packet of message
• Command sequence: number from corresponding uplink command (zero for autonomously generated messages)

The first data byte of packets for APID 5 and 23 (normal and high-priority command results), as well as APID 29 (traverse report) is the associated command code.

Rev C Changes:

• CCSDS fine time is no longer always zero. The fine time value is zero if standard rover software is running, but is set to 1 if Rover Lite is active.

1.2 Data Formats

Ordering of devices (motors, steering pots, etc.) is left-to-right, front-to-back (left front, right front, etc.).

• Position
  • X = mm north of lander reference
  • Y = mm east of lander reference
  • heading = BAMs clockwise from lander north (BAM = Binary Angle Measurement; 216 BAMs = 1 revolution)

• Attitude
  • Acceleration = reading * 0.0009765 g (I16 value) (where 1 g = 9.8m/sec2)
  • Acceleration = reading * 0.015625 g (I8 value, SIM Vehicle).
  • Acceleration = reading * 0.015625 g (I8 value, FUR Vehicle, before patch 50).
  • Acceleration = reading * 0.0078125 g (I8 value, FUR Vehicle, after patch 50).
  • Acceleration(min, max, avg) = reading * 0.015625 g (I8 value).
  • X/Y inclination = arcsine(accel / G) (where G = 1g on Earth, 0.38g on Mars)
  • Z tilt = arccosine(accel / G)
  • X accelerometer sensitive direction is aligned with +X (forward) axis, and indicates pitch (positive is front lower).
  • Y accelerometer sensitive direction is aligned with -Y (right) axis, and indicates roll (positive is left side lower).
  • Z accelerometer sensitive direction is aligned with +Z (down) axis.

  • Bogey/differential angle = reading * 0.08 degrees (I16 value).
  • Bogey pots read positive with front wheels lower than center wheels.
  • Differential reads positive with left side lower.
  • Steering/APXS mechanism angle = reading * 0.08 degrees (I16 value).
  • Steering angle = reading * 0.64 degrees (I8 value).
  • APXS mechanism angle = reading * 1.28 degrees (I8 value).
  • Steering pots read positive when wheel is turned counterclockwise (as viewed from above).
  • APXS pot reads positive when retracted, negative when deployed.

• Time
  • Long = U32 seconds (same as CCSDS time)
  • Short = U16 seconds (LS bytes of long time)
  • Tiny = U16 centons (secs/256)

• Temperature
  • Temperature is a non-linear function of resistance measurement.
  • 1109 ohms = -110 degrees C; 2609 ohms = 75 degrees C.
  • Bridge resistance = 1859 + (reading * 0.381) ohms (I16 value).
  • Bridge resistance = 1859 + (reading * 6.1) ohms (I8 value).

  • The temperature is nearly linear in the region of interest:
    • Degrees C = 2.4855 * (ohms/20) - 248.16
    • For I16 values: Degrees C = (raw reading/21.1199) - 17.1328
    • For I8 values: Degrees C = (0.7581 * raw reading) - 17.1328

  • Where all 13 sensors are reported, they are:

    	5     =     forced to "failed" state by command
    
    	8 and/or 16 may be added to the above values if the following bits are set:
    		8 (bit 3 set) = do not even think about turning on
    			this device (apparently shorted)

2. IMAGE DATA

The remaining packets contain a two-byte field indicating image width in pixels (allowing data to be correctly positioned even if packets are missing), followed by image data.

For uncompressed images, the data are raw image pixels (gray levels from 0=black to 255=white) in scanline order (first row left-to-right, next row left-to-right, etc.). All but the last packet of the message fill the available 1983 bytes, regardless of row boundaries.

For compressed images, the high-order bit of the width field is set. Data packets contain compressed image blocks (bitmask, mean, and deviation) encoding 16-pixel by 4-row sections into 13-byte blocks, stored in scanline order (first 4-row strip left-to-right, next strip left-to-right, etc.). All but the last packet of the message contain 152 blocks (the maximum whole number that fit in the available 1983 bytes), regardless of strip boundaries.

Rev C Changes:

• 3/05/97: "dev 81 FC: SPARE" previously decomm'ed into R-4082. Vehicle S/W now uses this "spare" telemetry element to transmit MAE Shorted Cell Current. Current value now decomm'ed into channel R-0325.
• 2/25/97: Deleted obsolete DMD page column
• Redundant channel (R-4083) for SPARE device failure count (device 82) removed
• 'alarm clock reset' and 'commanded reset' values swapped in definition of 'cause of last startup' telemetry
• Definitions of A/D reference levels (ground, -5V, +5V) modified from I8[3] to I8, U8, U8
• 82 device failure counts now defined
• Laser current description changed from 'direct' to 3.3V
• Motor heater set definitions added to telemetry description (channels R-231 to R-234)
• WEB heater channel assignment changed to channel R-235
• Modem heater telemetry description modified

5. TRAVERSE DATA

• 4/04/97: Added channel R-0511 as the unique channel for the contact state reported during each sample for the position APXS command whos common channel continues to be R-0517. Note that R-0511 is actually a previously defined common channel. Its use here as a unique channel is being done to workaround issues associated with the design of the decom algorithm ccsds_tlm and limitations in CCL.
• 4/04/97: Added channel R-0511 as the unique channel for the contact state reported at the end of traverse message. Note that R-0511 is actually a previously defined common channel. Its use here as a unique channel is being done to workaround issues associated with the design of the decom algorithm ccsds_tlm and limitations in CCL. The common channel for this particular contact value is now R-4091.
• 4/04/97: Added unique channel R-2303
• 3/03/97: Added unique channel R-2303
• 2/25/97: Deleted obsolete DMD page column.
• Corrected channel definition error in "Remaining Data" section of first packet:
  • R-120 replaces R-123 as left front motor temperature channel
  • R-121 replaces R-124 as right front motor temperature channel
• Replaced U8 heading telemetry with full U16 heading telemetry in BAMs in 'remaining data' telemetry in first packet
• Increased number of I8 laser spot offsets from 15 to 20 in 'goto waypoint' and 'find rock' command telemetry
• Deleted U8 proximity hazard indicator in 'goto waypoint' and 'find rock' command telemetry
• Added U16 contact sensor state (at end of last packet)
• Added U8 navigation hazard flags (at end of last packet)
• Added channel definition information for new contact sensor state and navigation hazard flags fields

6. MATERIAL ADHERENCE RESULTS

• 2/25/97: Deleted obsolete DMD page column.
• Channel R-1500 (differential QCM frequency) was incorrectly identified in the Telemetry Dictionary as an I16 value. This was corrected to U16.

7. WHEEL ABRASION RESULTS

• 3/03/97: Added unique channels R-3302 & R-3303
• 2/25/97: Deleted obsolete DMD page column.
• Channel R-1303 replaces channel R-1301. Previous channel caused wheel encoder data from right front wheel generated in traverse telemetry message to be intermixed with WAE telemetry from right center wheel.
• Channel R-0303 replaces channel R-0301. Previous channel caused wheel motor current data from right front wheel generated in traverse telemetry message to be intermixed with WAE telemetry from right center wheel.
