The Hemsiphere C321+ GNSS Receiver
Redesigned with construction environments in mind, the C321+ is the ruggedized version of the Hemisphere S321+. Just like the S321+, the C321+ is designed to quickly pay itself back, stay ahead of competition, and to last you for years to come.
Multi Constellation GNSS and Triple Frequency
The C321+ is Hemisphere’s multi-GNSS, multi-frequency smart antenna. With the Hemisphere C321+ you receive corrections from; GPS, GLONASS, Galileo, BeiDou, and SBAS constellations without a setup fee. To add to this, the C321+ is also triple frequency, meaning you have access to the most powerful GNSS signal yet, L5. The L5 signal is powerful enough to get through tree canopies, allowing you to get shots that you would otherwise not have been able to get.
The C321+ provides robust performance and high precision in a compact and rugged package. With a surveyor tough aluminum body, the C321+ is built to withstand whatever conditions you throw at it. The C321+ is built to survive a 2 M pole drop. This is the receiver that is built with accidents in mind, and is built to survive them. The IP67 environmental rating means that Hemisphere’s C321+ can withstand whatever conditions you face on site. This is the receiver that is built to last for years to come, and has the technology to compete that long as well.
Athena RTK Engine
The C321+ receiver is powered by Athena RTK technology. With Athena, C321+ provides state-of-the-art RTK performance: centimeter- level accuracy, near-instantaneous initialization times and functionality in the worst environments. With multiple connectivity options, the C321+ allows for RTK corrections to be received over radio, cell modem, Wi-Fi, Bluetooth, or serial connection.
The C321+ also boasts the impressive SureFix technology. With SureFix, you can always be assured that the solution you are seeing is the repeatable true solution.
With a subscription, the C321+ receiver also enables users to work with Atlas. Atlas is Hemisphere’s industry-leading global correction service, ensuring sub-decimeter positioning performance anywhere on earth.
Atlas L-band has the following benefits:
- Positioning accuracy – Competitive positioning accuracies down to 2 cm
RMS in certain applications.
- Positioning sustainability – Advanced position quality maintenance in the
absence of correction signals, using Hemisphere’s patented technology.
The C321+ features the industry-leading 1 W internal Satel radio that can send and receive corrections over both cell and UHF modems, even up to 3.5 km with no line of sight. The receiver fixes instantly almost every time we step out of the truck.
The internal 4G cell modem also allows you to send and receive corrections over cell, enabling our StormCaster internet RTK service. With StormCaster and an internal cellular modem, you can run an unlimited number of rovers of the same base at multiple different job sites.
In addition, the C321+ also broadcasts a Wifi signal over which setup and updates can be applied. The built-in Web-UI allows you to quickly set up static data, and base and a rover with little to no hassle.
