Track LoCARB

 

Value

Description

Speed Pixhawk sends speed as m/s. Multiplied by 1.944 to get Knots
Distance from launch How far LoCARB has traveled from the launch site in nautical miles.
Distance since last update How far LoCARB has traveled since the previous update in nautical miles.
Total distance traveled The total nautical mileage LoCARB has traveled since launch.
Heading Current heading in compass units (0-360, 0=north) provided by the Pixhawk
Batt Voltage Battery voltage as measured by the analog power module
State of Charge Voltage under Load
90% 12.55v
80% 12.50v
70% 12.37v
60% 12.24v
50% 12.11v

 

Current Amperage Used Battery current consumption as measured by the analog power module (Not very accurate)
Batt Capacity Remaining An estimate of the remaining battery capacity. Measured by the power module (ALWAYS WRONG)
Brain Box Temp DHT22 Temp reading taken from within the electronics enclosure. Houses Arduino, Arduino watchdog, Satellite modem, 2 channel relay, Breakout circuit board, and voltage regulator
Brain Box Humidity DHT22 Humidity reading taken from within the electronics enclosure. Houses Arduino, Arduino watchdog, Satellite modem, 2 channel relay, Breakout circuit board, and voltage regulator
Motor/Bat Pod Temp DHT22 Temp reading taken from within the Motor/Battery pod. Pod contains sensors, motor, 12v battery, and is fully submersed in water.
Motor/Bat Pod Humidity DHT22 Humidity reading taken from within the Motor/Battery pod. Pod contains sensors, motor, 12v battery, and is fully submersed in water.
Motor Temp DS18B20 measurement of motor mount. Sensor affixed with thermal glue.
Rudder Temp DS18B20 measurement of rudder casing. Sensor affixed with thermal glue.
GPS Lock 0 = No GPS connected
1 = No position information, GPS is connected
2 = 2D position
3 = 3D position
4 = DGPS/SBAS aided 3D position
# of Motor resets Motor monitoring function watches for 0 RPM. If detected, attempts to restart motor. Each attempt increments a counter, with every third attempt cycling power to the motor and ESC.
# of Capsizes SW520D Angle sensor detects tilt greater than ~60 degrees or VERY large collisions. Increments counter, resets after reaching 99.
# of times Pixhawk Reset The Arduino collects Mavlink heartbeat messages from the Pixhawk to detect a non-responsive state. If it receives none after 3 collection attempts, the Arduino will power cycle the Pixhawk and rudder servo. Resets after reaching 99.
Leak level in Bat Pod Cheap Ebay liquid level sensor to detect a leak in the motor/battery pod. Value of 0 or 1 (not incredibly reliable, so readings are a little inaccurate) is no leak, a value of 8 is ~2″ of water in pod.
Iridium location accurate to within Rockseven gives approximate GPS coordinates and distance accuracy (in km) with their message payload. Only shows up when viewing the ‘LoCARB (using Iridium approximate GPS coords)’ selection. Useful for comparing with LoCARBs much more accurate Pixhawk GPS coordinates. If coordinates are extremely different from the ‘LoCARB’ selection, it may signify a problem.
