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).
It also mounting an ultimate 3-axis digital compass, with selectable interface SPI or I2C (HMC5983).
This one is an high speed (220Hz output) and high resolution (2 milli-gauss) magnetometer.
