Why Choose us?

Back 40 Precision is an industry innovator not just a reseller or replicator. We hail a customer base reaching from North America, Europe, Asia and South America.

At Back40 Precision we manufacture models of GNSS receivers for the budjet minded and offer the highest technology available from Ag Leader® and SinoGNSS®. We also manufacture our RTKonnect ®  NTRIP client device with bluetooth and wifi capability.

Back 40 also has the most comprehensive RTK network service available today. Our entire network is capable TODAY of tracking and providing correction data for GPS, GLONASS and Beidou systems. Our cellular based GPS and Glonass RTK data is accessible through all of our top end base stations and our entire network.

Our own NTRIP Caster software is matched to the best in the industry. Our software allows the network operator to offer data in manually selected and automatically selected single baseline, as well as network data in the MAC, iMAC, and FKP formats. Our proprietary network calculations have proven to provide at or near subinch verticle accuracy at distances over 30 miles from the nearest reference station. (accuracy varies depending on the brand and technology of the rover being tested)

Customization is something else we are able to provide. Our early RTKonnect was a simple NTRIP client device however we have improved it time and time again by responding to requests of our customers for specific features. After implementing these changes they are incorperated into all current and future firmware versions for the device. If you need it, we can make it happen.
