HiPer SR GNSS Receiver

Daily setup routines are made easy with Topcon’s HiPer SR GNSS receiver.  It offers two options for communication between the base and the rover.  Intergrade license-free LongLink Bluetooth radio is perfect for smaller sites, or an optional cellular connection allows this unit to be a long-range receiver utilizing Topcon’s  Magnet Relay.  Many users prefer to use the SR as a Network rover as it is so small and light.  You can also combine it with a robotic total station system, to create a Hybrid solution ready for any environment.


The Topcon HiPer SR is an entry-level receiver that tracks both GPS and GLONASS satellites.  Like all Topcon receivers, it is made in the USA with a durable aluminum alloy shell and IP67 waterproof rating.  It can withstand a 1m drop or 2 m pole drop.  No matter what your site conditions are, the SR can handle it.

The SR can be used in a base rover set with Topcon’s interference-free Longlink communication.  This allows connection from 300 m (1000 ft) making it an optimal site receiver.  Other applications include using the SR as a rover in a base station network using cellular connections, or using a base and rover with cellular and Topcon’s Magnet relay.  This allows RTK ranges of up to 35 km.  This unit also pairs with the Topcon R4T-BT radio to make a low-cost addition to any Topcon UHF receiver.

The HiPer SR is a great way to get into GPS/GNSS GeoPositioning.  Whether you are a surveyor needing positioning options, a contractor looking to set up work sites, or even an MEP contractor looking to layout, the HiPer SR is an easy way to start.
