Native Data Description LDS Logger ID LDS Time Stamp [UTC] QC_Gravity: Cross coupling corrected gravity in mGal. Filter = Selected sec, time shift = Selected seconds. Digits of precision=9 Units = mGal Gravity: Uncorrected gravity. Filter= 5 sec, time shift =5 second Digits of precision=9 Units= mGal Long accelerometer: long accelerometer Filter=5 sec, time shift = 5 second Digits of precision=9, Units= Gal Cross accelerometer: cross accelerometer. Filter=5 sec, time shift = 5 second, Digits of precision=9, Units= mGal Beam: beam position in the range -5 to 5 volts from top to bottom stops, Filter=5 sec, Digits of precision=9, Units= volts Sensor Temp: Sensor Temperature in deg C. Filter=Selectable (typically 100 sec), Digits of precision=9, Units= deg C STATUS: Binary codified status word. Used to monitor the state of the sensor: Bit 0 =1 Meter Clamp Bit 1 =1 Meter Unclamp Bit 2 =1 The sensor has been GPS time synchronized Bit 3 =1 Feedback is ON Bit 4 =1 R1 (Not used in marine version) Bit 5 =1 R2 (Not used in marine version) Bit 6 = AD frequency locked ON Bit 7 = Command received from host computer Bit 8 = Platform controller Nav mode 1 Bit 9 = Platform controller Nav mode 2 Bit 10 = Not used Bit 11 = Serial com with sensor fail Bit 12 = Valid GPS NMEA string connected to GPS input Bit 13 = Sensor gravity input is saturated Bit 14 = Not used Bit 15 = Not used Checksum: Integer sum of all received values, used to detect transmission errors. Pressure: Internal sensor pressure. Filter=Selectable (typically 100 sec), Digits of precision=9, Units= inHg Etemp: Electronics temperature. Filter=Selectable (typically 100 sec), Digits of precision=9, Units= deg C Ve: Cross coupling monitor. Filter=5 sec, time shift =5 second, Digits of precision=9. Ve is calculated in the sensor as Ve = Kscale * Gravity^2 where Kscale is an arbitrary scale to make the monitor Ve be in the range of 0-20 for motions with vertical accelerations in the range 0 to 100 K mGals. Units= cm/sec Vcc: Cross coupling monitor. Filter=5 sec, time shift =5 second, Digits of precision=9. Vcc is overwrited with Vmon monitor. Units=cm/sec Al: Cross coupling monitor. Filter=5sec, time shift =5 second, Digits of precision=9. The monitor al is the product of vertical acceleration and longitudinal acceleration as recorded by the long accelerometer. This monitor is also scaled. Kscale m^2/sec^4 Ax: Cross coupling monitor. Filter-5 second, time shift = 5 second, Digits of precision=9. The monitor ax is the product of vertical acceleration and cross acceleration as recorded by the cross accelerometer. This monitor is also scaled. Kscale m^2/sec^4 Latitude: Read from the GPS NMEA RMC, Digits of precision=9, Units= Degrees Longitude: Read from the GPS NMEA RMC, Digits of precisiion=9, Units= Degrees Speed: Read from the GPS NMEA RMC, Digits of precisiion=9, Units= knots Course: Read from the GPS NMEA RMC, Digits of precisiion=9, Units= Degrees VMOND: Mean vertical velocity. 60 second filter. Digits of precision=9, Units= cm/s Year: Four digits year Month: 2 digits month Day: 2 digits day of the month Hours: 2 digits hours Min: 2 digits minutes Seconds: 2 digits second NumLine: integer up to 32 bits, number of lines sent from the start of the sensor
