Overview: The LandMarkTM 005 INS/GPS is a low-cost, non-ITAR commercial MEMS GPS-aided Attitude and Heading Reference System (AHRS) designed for various navigation applications. It features a 72-channel GPS with an 18 Hz position update rate and supports SBAS systems like WAAS, EGNOS, and MSAS.

Specifications:

• GPS Accuracy: ±2.0m CEP with SBAS, altitude accuracy of ±3 meters typical.
• Heading, Pitch & Roll Angles: Heading angle accuracy is ±0.5°, while pitch and roll angles are ±0.25°.
• Temperature Compensation: Fully compensated bias and scale factor over a temperature range of -40°C to +85°C.
• Gyro and Accelerometer Noise: Low noise gyros at 0.0028°/sec/√Hz and accelerometers at 0.071mg/√Hz.
• Power and Size: Operates on a low power of <825 mW and a low voltage of +5 V. It is lightweight (<80 grams) and compact (<35cm³).

Applications: Suitable for flight navigation, flight control, ship navigation, automotive testing, and laboratory use.

Performance Parameters:

• Inertial Performance: Standard full-scale ranges of ±490°/s and ±15 g’s, with a bias in-run stability of 5°/hour.
• GPS Performance: Autonomous horizontal position accuracy of 2.5 m, velocity accuracy of 0.1 m/s, and a start-up time of 27 seconds for cold starts.
• Environmental Tolerance: Operating temperature range from -40°C to +85°C and storage temperature from -55°C to +100°C.

Physical Characteristics: The device is rugged and environmentally sealed, ensuring durability in various conditions.

Messaging Protocol: The system uses a checksum byte for error checking, with data transferred in little-endian format. The total transport time per message packet is 5.2ms.
