Rugged, Palm-sized Sub-Decimeter OmniSTAR®
L1/L2 RTK GPS Receiver The SXBlue III-L GPS is a compact GPS receiver that delivers sub-decimeter accuracy anywhere in the world using OmniSTAR®’s HP service. Its integrated lightweight design makes it the ideal choice for a variety of applications including GIS, Mining, Construction, Utilities, Agriculture, Surveying and Environmental, at a price you can afford. In addition to OmniSTAR, the SXBlue III-L is also capable of traditional RTK and post-processing for centimeter-level accuracy.

A Long Term Flexible Solution

Add a field computer that suits your application, and off-the-shelf software of your choice, and the SXBlue III-L GPS becomes the heart of a modular solution you can grow with. In today’s rapidly evolving computer technologies, its unique multi-port interface (independent Bluetooth, USB and RS-232 ports) helps to protect your long term investment by always allowing the use of up-to-date computer hardware, operating system and software. The SXBlue III-L GPS maximizes your productivity by working directly within your framework (Esri, Autodesk, Carlson, CMT, Intergraph, MapInfo, Digiterra, etc) both in the field and in the office.

Worldwide Real-Time, All the Time!

The SXBlue III-L GPS uses innovative technology that puts dual frequency GPS, OmniSTAR, SBAS and RTK Network signals in one of the smallest packages ever. You get 51 channels of proven high accuracy real-time performance from a lightweight unit that fits in the palm of your hand. The SXBlue III-L GPS supports RTK base and rover configuration for places where real-time centimeter accuracy is required and no RTK Networks are available. In addition to OmniSTAR and RTK, you also have the option of using L1 SBAS (WAAS, EGNOS, MSAS, GAGAN) for sub-meter mapping that the SXBlue has built its reputation on. Having the choice of OmniSTAR VBS/XP/HP, L1/L2 RTK or L1 SBAS for real-time mapping provides you with the flexibility that no other unit of this size and price can offer you.

Sub-Decimeter Real-Time Accuracy with OmniSTAR HP

OmniSTAR offers worldwide over-the-air correction services via a subscription. The SXBlue III-L GPS is capable of achieving 10cm (4 in) accuracy using the OmniSTAR HP service, 20cm (8 in) with the OmniSTAR XP service and submeter with the OmniSTAR VBS service. The VBS service can be used in areas where no free SBAS (WAAS, EGNOS, MSAS, GAGAN) signal is available. It is ideal in all applications where submeter is sufficient. The SXBlue III-L GPS also provides with superior tracking performance and unique innovative real-time positioning that means no downtime even in the harshest conditions, making it ideal for a full-day DGPS work even under forest canopy.

Real-time Centimeter Accuracy with L1/L2 RTK

When higher accuracy than decimeter is required for your job, the SXBlue III-L GPS offers optional support for RTK (Real-Time Kinematic). If an RTK network is available in your area, you may activate the RTK Rover option on your SXBlue III-L GPS and connect to the network via a wireless link to achieve 1cm accuracy within seconds. The SXBlue III-L GPS also features the option to be used as a local RTK base station to output standard and proprietary differential correction formats such as RTCM 3.x, ROX and CMR.
