VR GPS Ublox Lea 6H with HMC5983 Magnetometer

 

First Virtualrobotix GPS engine using Ublox LEA-6H receiver.

This is a 50-channel high sensitive engine that boasts a Time-To-First-Fix (TTFF) of less than 1 second.

Also provide a rechargeable backup battery to improve warm start.

The dedicated acquisition engine, with over 2 million correlators, is capable of massive parallel time/frequency space searches, enabling it to find satellites instantly.

Innovative design and technology suppresses interference sources and mitigates multipath effects, giving LEA-6H GPS receivers excellent navigation performance even in the most challenging environments.

Virtualrobotix GPS uses an high efficient low noise amplifier to improve antenna signal (19dB) and a SAW filter to select GPS frequencies (see graph below).
