True North Path Finder

Product catalog summary

Overview: The document describes the GNSS Based North Alignment System, known as the True North Path Finder. It provides position, speed, time, heading, and pitch angle using two GNSS antennas to determine true North in both static and dynamic conditions.

Connector and Power Details: The system requires a 9-36V DC power supply and supports GPS/GLONASS/Beidou/IRNSS active antennas with a maximum of 5.5V/100 mA. It includes multiple communication ports and supports data formats such as NEMA 3.0 and RTCM SC104 Ver 2.1, 2.3.

Features: The system supports multiple GNSS constellations including GPS, NavIC, GLONASS, Beidou, and SBAS-GAGAN. It is built to meet military standards (MIL STD) and offers rugged construction. The system provides NMEA 3.01 output messages and isolated serial ports, with dual antenna capability and a 10/100/1000 Ethernet interface.

Technical Specifications: The system operates within a temperature range of -30°C to +70°C and can be stored between -40°C to +85°C. It is designed to withstand shocks as per MIL-STD-810G standards. The device dimensions are 147x125x55 mm, with a weight of less than 1 kg. It supports a maximum velocity of 515 m/s, acceleration of 4g, and altitude of 18,000 m.

Accuracy and Performance: The system offers high accuracy with a baseline requirement of 1m minimum between antennas. Positioning accuracy varies with different modes: standalone mode (1.5m horizontal, 2m vertical), SBAS (<1m horizontal, 1m vertical), DGPS (0.25m horizontal, 0.5m vertical), and RTK (5mm + 0.5ppm horizontal, 8mm + 1.0ppm vertical). The heading accuracy is <0.4° and pitch/roll accuracy is <0.5°.

Mechanical and Environmental Specifications: The chassis is made of Aluminium 6061-T6 with an olive drab color. The system uses passive conduction cooling and is designed for flange mount installation. The Mean Time Between Failures (MTBF) is 182,682 hours.

Ordering Information: The document lists part numbers for the device, antenna, and cable: Device P/N: V3N-TNPF-V3.0, Antenna P/N: V3N-GGI-121-01-10, Cable P/N: V3N-RF-LMR240-15-15-15M.

True N#rth Path Finder GNSS BASED NORTH ALIGNMENT SYSTEM * Multi GNSS Receiver Supporting. * Rugged construction to meet MIL STD. * NMEA 3.01 Output Message * RTCM Output Message * Isolated Serial Ports * Dual Antenna Capability Our True North Path Finder will provide position, speed, time ,heading and pitch angle. System use the position measurement of two GNSS antennas to determine true North in both static and dynamic condition. In order to achieve high Accuracy baseline between the two GNSS antennas must be very constant. Both GNSS antennas have to observe the same GNSS satellites at the same time. Our System consists of GNSS Head -ing Receiver along with High Accurate Antenna with Multi path Rejecti on capability to achieve better Heading and Positional Accuracy.
