VR GPS uBlox 8

Description

First Virtualrobotix Multi Constellation GPS engine using Ublox NEO  8 receiver.

This is a 72-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 NEO-8 GPS receivers excellent navigation performance even in the most challenging environments.

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.
