Performance Upgrade Path
The SF-3050 is designed with a robust and long-term performance upgrade path to meet changing application needs via software optioning alone. Increased functionality does not require the costly purchase of a new receiver. The SF-3050 software-enabled features, bundled or purchased individually, cover a wide variety of applications.
Over the Air StarFire Licensing
Over The Air StarFire Licensing is the easiest way to install a StarFire license. The installation of a purchased license is accomplished via radio broadcast. Over The Air StarFire Licensing is especially convenient for receivers in remote locations in the field.
GNSS Performance
Sapphire, the SF-3050’s engine, is a 66 channel GNSS with the required flexibility to track all civilian GNSS and SBAS signals (GPS & GLONASS) with integrated StarFire signal tracking. Sapphire’s industry leading receiver sensitivity provides more than 50% signal to noise ratio advantage over competing technologies. This results in improved real time positioning, proven through independent tests, when facing various multipath environments.
High Precision
Coupled with our StarFire subscription service, the SF-3050 delivers 5 cm position fixes without the use of a secondary receiver. Add our RTK option and an external radio capable of receiving RTK corrections from a base station, and the SF-3050 is able to perform RTK-level surveys for unsurpassed accuracy. On-board memory (2GB) and a geodetic-quality antenna enable millimetre-level accuracy from post-processing.
