SPEEDBOX20 / Specification

SPEEDBOX20 Specification

GPSOutputs position, speed, position accuracy, speed accuracy and heading every 50ms with no interpolation. GPS tracking loops optimised for applications up to about 4g. Tracks all satellites in view.
GPS AntennaMagnetic base, 3.3v active antenna with SMA connector.
Power Supply Requirements12v nominal input, minimum of 10v, maximum of 15v. Current consumption approximately 200mA @ 12V
Case ConstructionCNC machined billet aluminium, anodised black, sealed to IP65 standard
Connector TypeSMA female bulkhead connector for GPS antenna, Binder 723 series 12-way male bulkhead connector to supplied wiring harness for all other connections. Sealing better than IP65.
Main ProcessorHigh performance 200MHz TI DSP
Serial Output2-Axis acceleration and combined speed output at 200Hz. GPS position, GPS speed, GPS heading, GPS altitude and GPS time output at 20Hz. RS232 voltage levels using standard Race Technology format. 115.2 kbaud
CAN Output2-Axis acceleration and combined speed output at 200Hz. SPEEDBOX20 status, GPS position (lat/long/altitude and ECEF X/Y/Z formats), GPS position accuracy, GPS velocity, GPS velocity accuracy, GPS time, GPS heading and number of satellites used in GPS solution output at 20Hz. RTK option also outputs yaw, pitch, slip, estimated baseline and estimated accuracy at 20Hz. Output at 3.3V level, 11 or 29-bit addressing, user configurable addressing and baud rate (125/250/500kbps/1Mbps).
Analogue OutputLongitudinal acceleration, lateral acceleration, combined speed (RTK option outputs yaw, pitch and combined speed), 0-5V output level. User configurable scaling of combined speed output from 10m/s to 500m/s FSD.
Pulse OutputFrequency proportional to combined speed, pulse at 5V, user configurable from 10 to 1000μs or 50% duty cycle. User configurable pulse rate: 1-400 pulses per metre. Output impedence 50Ω, minimum recommended termination impedance 1kΩ.
Accelerometers2-axis, precision digital output. Guaranteed 2g minimum full scale on both axes, 6g option available. Resolution of 0.001g.
VibrationFactory tested at 25g, 50Hz sinusoid for 5 minutes
TemperatureFactory tested from -20C to +70C

"WARNING": To avoid any possible damage to the car paintwork, please take care when mounting magnetic GPS antennas. In particular make sure that there are no dust or grit under the antenna. In some cases it maybe required to add additional protection to the paintwork prior to mounting the antenna to avoid damage.
