HiPer Ga

HiPer Ga

The HiPer Ga features GPS satellite tracking capability standard, with the added bonus of optional GLONASS satellite tracking upgradeability via OAF activation code. Software-based OAF upgradeability means there’s no hardware changes or modifications required. Your local Topcon dealer can upgrade your HiPer Ga while you wait in most cases.
The HiPer Ga can be configured as a cable-free base and rover system for traditional applications, or as two rover receivers from a fixed base station or a GNSS network system, via radio or cellular communication.

HiPer Gb

HiPer Gb

The HiPer Gb provides similar hardware functionality to the Ga, but with GPS only tracking capabilities. The HiPer Gb is a very economical or can be used as a two rover system working from a fixed base station (UHF broadcast reference capability only). The HiPer Gb provides a fully functional GPS RTK system that can also be used for traditional static observations, at a price that fits any budget.

If you’re looking for an Simple and Easy RTK solution that provides advanced technology, wireless system design, and rugged, waterproof construction look no further. Topcon’s Green Label HiPer Ga and HiPer Gb are the cost-effective answer you’ve been waiting for!
