Topcon Positioning Systems has unveiled the HiPer SR — an advanced GNSS RTK receiver that Topcon describes as having “the most compact and lightweight design of any fully integrated precision receiver — ever.”
With the HiPer SR, Topcon is expanding the delivery of high-accuracy RTK technology to a variety of users — surveyors who need a tool for small boundary or stakeout work, non-traditional users such as landscape architects who need a low-cost mapping solution, and law enforcement or any others requiring high-accuracy 3D positioning.
Cable-free and weighing under 2 pounds, the rugged and fully integrated design delivers a 1,000-foot working radius through Topcon’s new LongLink technology. The LongLink wireless data link was developed specifically for the HiPer SR, and provides reliable and interference-free RTK base-to-rover communications that don’t require an FCC license to operate, Topcon said. Base and rover units can be used interchangeably.
The HiPer SR can also be a dedicated network rover. All standard RTK correction formats and network protocols are supported, and a comprehensive range of field workflows are realized with the Magnet family of cloud-enabled software solutions.
The HiPer SR’s 226-channel Vanguard GNSS chip provides precision measurement and advanced multipath rejection, offers support for all modernized GNSS constellations, and incorporates Topcon’s patented Universal Tracking Channel technology whereby any channel can track any available signal, reducing power consumption and system weight. As more GNSS signals come online, this flexibility enables the 226-channel Vanguard design to scale up and track more signals than other GNSS systems.
Additional features of the HiPer SR include:
- Quartz Lock Loop technology. Designed by Topcon engineers for superior GNSS tracking in high-vibration environments, such as on a four wheeler;
- Capable of simultaneous LongLink operation with multiple rovers;
- Sealed battery pack provides more than 15 hours of operation;
- Lightweight and shock-resistant magnesium alloy housing, allowing the HiPer SR to take a 6 ft. (2m) pole drop onto concrete
