Atlas is Hemisphere GNSS’s new L-Band GNSS correction service, offering an innovative service that provides performance that meets or exceeds that delivered by other industry leaders, at market-leading prices.

Atlas L-Band service is the most flexible service on the market, delivering its correction signals via L-Band satellites or over the Internet at accuracy ranging from sub metre to sub-decimeter levels. With approximately 200 reference stations worldwide and L-Band satellites distributing coverage from 75°N to 75°S to ensure all of the earth’s landmass is covered.

There are 3 subscription levels - H10 gives approx. 10 cm accuracy. H30 gives 30cm accuracy and the Atlas basic gives 0.5m accuracy which is much the same accuracy when using the AMSA marine beacon. Please ring for a cost on the Atlas service.

The Atlas subscription supports the below Hemisphere GNSS receivers. The Atlas Link, the R330, VS330 and the S321.

The Hemisphere S321+ is a multi-GNSS, multi-frequency all on the pole receiver. The S321+ provides a robust field performance and high precision in a compact and rugged package. With multiple wireless communications ports and an open GNSS interface, the S321 can be used in a variety of operating modes.

S321+ as a Network only bundled package with no internal UHF radio installed - $11,100 exGST.

S321+ with the UHF radio module installed and UHF antenna - $13,900 exGST.

The S321+  ships with the following equipment.

6 month’s Atlas H10 Subscription – included with purchase.
2 x Batteries for the S321 (one spare)
1 x Desktop battery charger
1 x Serial Cable for PC or Hand Held Controller
1 x Tape measure
1 x GPRS Antenna

The Hemisphere R330 GNSS receiver provides a full surveying solution product in a compact rugged enclosure. It has a front screen to display information and buttons to configure the receiver without the need for a data controller. It receives all the current satellite constellations. It can provide 1cm accurate positioning when in RTK mode and 0.3m accuracy when using the free to air marine beacon or SBAS signal.

The R330 GNSS receiver works well in any marine or land application where positioning accuracy is required. The base unit is configured with L1, 10 Hz, SBAS, and raw data. It can be optioned with the following features L1/L2 GNSS, 20 Hz, RTK, L-Band, Marine Beacon, and SBAS. Compatible GNSS antennas for the R330 are A21, A31, A42, A43, A45 and the Geodetic A52.

R330 Receiver is $6,500 exGST

And ships with the following components / features:
1 x Eclipse R330U Receiver
1 x R/VS Series Mounting Assembly
1 x Eclipse 10 Hz activation
1 x 3m Power Cable w/ Fuse
1 x 3m USB A Cable
1 x 3m RS232 Cable

The Hemisphere VS330 GNSS receiver is similiar to the R330 but acheives accurate course heading by using two (2) GNSS antenna. It has a front screen to display information with buttons to configure the receiver without the need of a computer. It receives all the current satellite constellations. The VS330 can provide 1cm accurate positioning along with accurate heading. It is used in the marine industry instead of a gyro compass as it can provide accute heading even when the boat is reversing backwards. It is accurate to 1 cm when in RTK mode, 10cm accuracy when using the Atlas H10 subscription and 0.3m accuracy when using the free to air marine beacon or SBAS signal.

VS330 L1 GNSS receiver [10 Hz, sFreq, mGNSS] Atlas Capable is $9,000 exGST
VS330 L1/L2 GNSS receiver [20 Hz, mFreq, mGNSS, RTK] Atlas capable is $11,500 exGST

The VS330 ships with the following components.
1 x R/VS Series Mounting Assembly
1 x 10m coaxial antenna cable
1 x VS330 interface cable
1 x 3m Power Cable w/ Fuse
1 x 3m RS232 Cable

The Atlas Link is Hemisphere's GNSS Smart Antenna which uses the 3 main satellite constellations USA's GPS, Russia's 'GLONASS' and China's 'BeiDou'. An approximate cost for this receiver is $4,500 exGST.
