GPS Receiver and Heading Sensor

A GPS receiver and heading sensor is a combined navigation instrument that provides simultaneous position data and directional orientation output for platforms requiring both location tracking and bearing information in a single integrated unit. The GPS receiver component acquires signals from GNSS satellite constellations including GPS, GLONASS, BeiDou, and Galileo depending on the module specification, calculating position fixes with horizontal accuracy ranging from 2.5 meters on standard single-frequency receivers to sub-centimeter levels on RTK-enabled dual-frequency models. The heading sensor component uses either a dual-antenna GPS baseline, a magnetometer array, or a MEMS gyroscope depending on the system design to determine the true bearing of the platform independent of movement.

Dual-antenna GPS heading systems derive directional information by calculating the vector between two spatially separated antenna positions, providing heading accuracy typically between 0.1° and 0.5° RMS depending on antenna baseline length. This method is unaffected by magnetic interference from vehicle structures or nearby metallic objects, making it more reliable than magnetometer-based heading sensors in metallic platform installations. Update rates for combined position and heading output range from 1 Hz on standard units to 100 Hz on high-dynamics models used in rapidly maneuvering platforms.

Output interfaces include RS-232, RS-422, USB, and Ethernet with NMEA 0183 and binary proprietary data formats supported across most professional units. Power consumption ranges from 1.5W to 8W depending on the receiver grade and active antenna requirements.

In Pakistan, GPS receiver and heading sensor systems are used in military vehicle navigation, UAV ground control and autopilot integration, marine vessel navigation on river and coastal routes, and survey equipment orientation for GPR, total station, and geophysical instrument platforms.

Tactical Supply Pakistan supplies GPS receiver and heading sensor units for defense navigation, UAV systems, survey equipment, and vehicle tracking applications across Pakistan.
