I'm very happy to present the result of latest VirtualRobotix's development: the new VRX GPS NEO-M8 .
I'ts the first Virtualrobotix's Multi Constellation GPS (GPS, GLONASS, Galileo, QZSS and SBAS), engine, using Ublox NEO-M8 receiver.
The NEO-M8 is a 72-channel high sensitive engine that boasts a Time-To-First-Fix (TTFF) of less than 1 second.
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-M8 GPS receivers excellent navigation performance even in the most challenging environments.
VRX GPS NEO-M8 is equipped with a Panasonic Amplifier for better reception and a backup battery for quicker warm restarts.
The VRX GPS NEO-M8 also integrates Honywell's latest high precision digital mag (HMC5983).
The HMC5983 can be used either in SPI or in I2C (selectable via a solder Jumper), it has a 200Hz output rate and it's temperature compensated, giving the best experience for our vehicles.
The VRX GPS NEO-M8 is fully compatible with APM:Copter's firmware and it's plug and play on VRBRAIN5, VRuBRAIN5, APM 2.5+, PixHawk and all boards that mount the DF13 connectors.
If you don't have a DF13, you can easly solder standard servo pins on the exposed pads.

The VRX GPS NEO-M8 has been tested in the field with our VRX300 "Personal Fly Robot SDK Platform" here are some photos and graphs from latest flights.
Flight Controller: VR Micro BRAIN
GPS: VRX GPS NEO-M8
Compass: HMC5983 mounted on GPS board
ESC: 12 A Kiss ESC

These are the vibration graphs on the VRX300
The number of satellites during this flight started at 11 and arrived to 15, the hdop was from 1.3 to 1.5.
During my tests we have seen up to 18 satellites with an hdop of 0.7 .
With standard GPS module some times it is possible to see only 5 with an high HDOP
Here is possible to see the Altitude from Baro vs Altitude from GPS is not so bad :)
Some RTL and Loiter tests in the Field with precision of less than 1 meter.
