The RUSHFPV GNSS MINI is a compact GPS module that makes use of the newest u-blox M10 ultra-low-power platform. It’s appropriate for FPV drones and fixed-wing planes. It’s suitable with BetaFlight and iNAV flight controller software program. To offer worldwide protection, it will probably work with all main satellite tv for pc positioning suppliers (GNSS), together with GPS (International), GLONASS (Russian), BDS (China), and GALILEO (Europe).
Why do you want a GPS module in your FPV drone?
GPS modules are usually not important FPV drone components, however they’re crucial in case of RX sign loss. They supply real-time telemetry information akin to flight altitude, distance, and velocity, permitting you to configure your plane in BetaFlight or iNAV with autonomous flight modes.
FPV drones can value from a number of hundred to some thousand {dollars}, and also you wouldn’t need to lose them if one thing had been to occur with radio or video communication. The most affordable GPS module proper now could be round 10 bucks and can enable your drone to return to the take-off level in case of RC sign loss (Rescue mode) or a guide set off by the pilot. If you happen to determine to improve your drone with GPS, I extremely advocate utilizing the newer M10-based GPS choices over the older Beitian BN220 chips.
RUSHFPV GNSS MINI GPS module for FPV drones
Disclosure: I obtained this GPS module as a part of a product evaluation collaboration with RushFPV. Though the product was free, all opinions on this article stay mine, and the sponsor didn’t affect me.
RUSHFPV is thought for its high-performance VTXs, however currently, it has began producing flight controllers, ESCs, AIOs, and GPS modules, overlaying nearly all important elements of an FPV drone.
The RUSHFPV GNSS MINI is available in a nylon bag with a QR code to entry the consumer guide. The module measures 18x18x4.8mm and weighs barely greater than 4 grams. It has two standing LEDs (Prepared and Energy) and 4 solder pins (RX, TX, 5V, and GND) for connecting with the flight controller. The ceramic antenna measures 18x18mm, and while you set up the module in your drone, it must face the sky with out being obstructed by steel components of the drone. Suitable TPU mount 3D STL recordsdata might be discovered on Thingiverse.

Small measurement, light-weight, quick positioning, and steady connection;
For positioning modes: GPS, BDS, GLONASS and GALILEO
Extremely-low-power u-blox M10 platform

Efficiency
The efficiency of a GPS module is set by two elements: how briskly it will probably repair eight satellites (really useful for BetaFlight Rescue) on chilly begin (hasn’t been powered on for at the least 12 hours) and scorching begin (hasn’t been powered on for lower than an hour) and what number of satellites it will probably repair after 5 minutes of being powered.
Throughout my assessments, the RUSHFPV GNSS MINI discovered 8 satellites after 1:41 on chilly begin and after 27 seconds on scorching begin. After 5 minutes of flight, it discovered 17 satellites, which is affordable for my area.
Value and availability
The RUSHFPV GNSS MINI might be ordered immediately from the producer’s official retailer or different retailers for $13.99. If you happen to want a built-in compass, the extra versatile but in addition greater and heavier GNSS Professional modules are priced at $15.36.
RUSHFPV GPS modules collection comparability
RUSHFPV has three GPS modules, two with out a built-in compass and one with an built-in HMC5883 three-axis digital compass. The GNSS Micro module measures 12x15x4.8mm and weighs 2.4g, and the GNSS Mini 18x18x4.8mm weighs 4.2g. The GNSS PRO measures 25x25x4.8mm and weighs 6.9 grams. Technical parameters akin to variety of receiving channels and satellite tv for pc supplier compatibility are an identical. Because of the built-in compass, the GNSS PRO has two further pins (SDA and SCL) along with the RX, TX, 5V, and GND.
