data_engineering_raw 195 PDS DSV 1 Raw Engineering Data from NSS aboard Astrobotic Peregrine Mission-1 Lander 6986 Carriage-Return Line-Feed Comma 11 0 datetime 1 ASCII_Date_Time_YMD UTC Date time when record was collected, YYYY-MM-DDTHH:mm:ss.fffZ format, example : 2024-01-08T14:02:31.595Z adc_reference_raw 2 ASCII_Integer Number that, when multiplied by 0.0129, results in the analog-to-digital converter reference voltage. fpga_core_raw 3 ASCII_Integer Number that, when multiplied by 0.0129, results in the Field-Programmable Gate Array core reference voltage. fpga_io_raw 4 ASCII_Integer Number that, when multiplied by 0.0259, results in the Field-Programmable Gate Array Input/Output reference voltage. fpga_version 5 ASCII_Integer FPGA firmware version number. Nominal is ‘1’. front_end_raw 6 ASCII_Integer Number that, when multiplied by 0.0775, results in the front-end electronics voltage. power_supply_raw 7 ASCII_Integer Number that, when multiplied by 0.0259, results in the low-voltage power supply voltage. sensor_module_pwr_onoff_status 8 ASCII_Integer Power state of sensor module. Derived from byte 68, bit 4. 0 is off, 1 is on. watch_dog_reset_indicator 9 ASCII_Integer Indicator of a watchdog reset of the instrument. 1 = reset has occurred. command_counter 10 ASCII_Integer Counts/bin Number of commands received since last power-on (0 – 15 then roll-over). telemetry_frame_counter 11 ASCII_Integer Counts/bin Sequential number of telemetry frames transmitted over RS422 (0 – 63 then roll-over).
