New High-Accuracy RTK system – Topcon HiPer SR – Tough and Affordable Print E-mail
Written by Topcon Positioning Systems   
Friday, 17 August 2012

Livermore, Calif.  – August 17, 2012 – Topcon Positioning Systems (TPS) announces the new HiPer SR – a highly advanced GNSS RTK receiver with the most compact and lightweight design of any fully integrated precision receiver - ever.

The Ultimate Job Site Solution
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, law enforcement or any others requiring high-accuracy 3D positioning.

Topcon, who led the precision RTK receiver industry with the first ever fully integrated systems, continues to set the standard with state-of-the-art devices combining leading technology in ultra-compact designs. Cable-free and simple to operate, the HiPer SR is the most compact professional-grade base and rover RTK system available.  The field-rugged and fully-integrated design delivers a 1,000-foot working radius through Topcon’s new LongLink™ technology.  This innovative 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.  Base and rover units can be used interchangeably.

Lightweight Network Rover
The HiPer SR is also offered as a dedicated network rover, and at only 1.8 pounds (0.8kg) – is the lightest full-precision system available.  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.  Topcon’s Universal Tracking Channel™ technology combined with the HiPer SR’s 226-channel Vanguard™ GNSS chip provides the ultimate platform for network RTK performance, both for today and in the future.
Advanced Topcon Technology
 Topcon’s Vanguard GNSS chip is at the “heart of the HiPer SR.”  In addition to precision measurement and advanced multipath rejection, the chip offers support for all modernized GNSS constellations and incorporates Topcon’s patented Universal Tracking Channel technology.  While other GNSS receiver designs must dedicate channels to a specific satellite system or signal – requiring more and more channels as additional GNSS signals become available – with Universal Tracking Channels, any channel can track any available signal.
This powerful capability enables the multi-constellation tracking that professionals expect – but with lower power consumption and system weight.  Additionally, 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.
“We took the best signal tracking technologies available – including Topcon’s Vanguard GNSS chip and Fence Antenna™ – and packaged them in a small, energy-efficient design,” said Fraser Smith, TPS director of GNSS products.  “Anyone looking for a rugged, easy-to-use, low-cost 3D mapping system will find what they need in the HiPer SR.”

Additional key 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.
