The new Gnd-r5 module incorporates a "mems" technology inertial sensor that continuously captures the vehicle's direction and processes it in real time with the distance traveled information captured from the vehicle's odometer.
The Gnd-r5 module is inserted between the GPS UART and the system MCU UART. When the information received from the GPS module does not contain a valid location, the Gnd-r5 module replaces it with an equivalent frame containing the vehicle's location calculated by its Dead Reckoning algorithm, maintaining position information as if it were still receiving a perfect signal from the GPS satellites.
Technical Specifications of the Gnd-r5:
• Self-calibration
• 3.2V to 3.6V power supply (3.3V typical)
• Low power consumption: 20mA at 3.3V
• Dimensions: 17x22.4x2.2mm
• Communication speed up to 115Kbps
Main applications:
Vehicle location in tunnels, underground parking lots, metal bridges and urban environments with very tall buildings that prevent the correct reception of GPS signal.
