RTSS Technical Specification

Data Upload mobile data network connection to online cloud storage
Internal Memory 64Mbyte, enough to buffer over 12 hours of data when there is no mobile data network connection
Memory card Removable SD card up to 32GB
Maximum No Channels No hard limit, potentially 100s
SIM Card User accessible, any data SIM can be used
Telemetry Update Rate Typical update rate to website browser is 5Hz, live data upload to PC software is 10Hz. Cloud 100Hz.
GPS Outputs position, speed, position accuracy and speed accuracy at 5Hz with no interpolation. GPS tracking loops optimised for applications up to about 4g. tracking of all satellites in view.
GPS Antenna 3.3v active antenna with SMA connector.
Analogue Inputs 10 external inputs, 0-25v. All inputs are protected and have a 2nd order filter with corner frequency of 105Hz. Accuracy = 0.4% of measured voltage +-20mV. Sample rate 100Hz as standard, 1kHz optional.
Frequency Inputs 4 external frequency inputs with a maximum input frequency >2kHz. Triggering voltage requires a low input of <1v and a high input of >4v and 15v maximum.
Low level outputs 4 low side drivers updating at 10Hz, each capable of driving 500mA.
Power Supply Requirements 12v nominal input, minimum of 10v, maximum of 20v. Current consumption of about 300mA.
+5v Ref +5v +-1.5% output for powering sensors Maximum current draw 500mA x 2.
+8v Output +8v +-5% output for powering sensors. Maximum current draw 250mA. (Low noise output)
