The telemetry is split into up to 3 CW beacons and 3 HS beacons. Together they form a snapshot of the sensors. Each 9k6 FSK broadcast contains the data of the CW beacon. If the battery voltage falls below a critical value, only CW telemetry is sent.

CW Beacon 1

ABCDEFGHIJKLMNOPQ
A - Beacon sequence
BC - MPB Voltage (V * 0.2)
DE - HPB Voltage (V * 0.2)
FG - Battery 1 Voltage (V * 0.2)
HI - Battery 2 Voltage (V * 0.2)
JK - Battery 1 Current Generated
LM - Battery 1 Current Absorbed
NO - Battery 2 Current Generated
PQ - Battery 2 Current Absorbed

CW Beacon 2

ABCDEFGHIJKLMNOPQRS
A - Beacon sequence
BC - Battery 1 Temperature (signed int)
DE - X+ Temperature (signed int)
FG - X- Temperature (signed int)
HI - Y+ Temperature (signed int)
JK - Y- Temperature (signed int)
LM - Z+ Temperature (signed int)
NO - Z- Temperature (signed int)
PQ - RFamp Temperature (signed int)
RS - Battery 2 Temperature (signed int)

CW Beacon 3

ABCDEFGHIJKLM
A - Beacon sequence
BC - Solar Panel Current X+ (I*10)
DE - Solar Panel Current X- (I*10)
FG - Solar Panel Current Y+ (I*10)
HI - Solar Panel Current Y- (I*10)
JK - Solar Panel Current Z+ (I*10)
LM - Solar Panel Current Z- (I*10)
