Geneq Inc. has announced the SXBlue II GNSS, a GNSS receiver that uses both GPS and GLONASS with SBAS (WAAS/EGNOS/MSAS/GAGAN) to attain 30-cm/1-foot (RMS) accuracy in real-time using free SBAS corrections. It connects wirelessly to any smartphone, handheld, tablet computer, or notebook computer that is Bluetooth-compliant.

For years, the SXBlue GPS product line has lead the market in squeezing the most out of SBAS for high-precision mapping and surveying users. New technology used in the SXBlue II GNSS allows it to utilize both GPS and GLONASS with SBAS, enabling it to track and use nearly twice as many satellites compared to typical SBAS receiver technology.

“More satellites means more accurate positioning in tougher environments, such as under tree canopy and near buildings,” said Jean-Yves Lauture, product engineer. “GLONASS has proven itself valuable for RTK, and now we are bringing GLONASS to SBAS, with impressive accuracy and tracking results.”

The SXBlue II GNSS builds on the success of the proven SXBlue II GPS that was designed to optimize SBAS performance under tree canopy and in rugged terrain. With the ability to track 55 satellites (31 operational GPS, 24 operational GLONASS), the SXBlue II GNSS uses between 12 and 19 satellites in view at any time, providing superior performance when working under and around tree canopy, buildings, and rugged terrain, Geneq said.

The next-generation SXBlue II GNSS is the same, small, palm-sized unit as the SXBlue II GPS and uses a small 2.7-inch diameter GNSS antenna. The unit is completely waterproof (submersible), dustproof, and ruggedized, with an IP-67 rating. Its Class 1 long-range Bluetooth 2.0 has a typical range of 250 meters. The internal, rechargeable, field replaceable Li-Ion battery has on-board LEDs let the user know how much battery life is left. The operating temperature range of the SXBlue II GNSS is -40°C (-40°F) to 85°C (185°F).

In addition to the built-in long-range Bluetooth transceiver, the SXBlue II GNSS has a standard DE-9 RS-232 port and a USB Type B port with outputs fully programmable up to 10-Hz standard, with a 20-Hz option. Other optional features are L1 RTK for <2-cm real-time accuracy and base station RTCM output.

There is no need for post-processing or other sources of differential corrections as the SXBlue II GNSS uses WAAS (North America), EGNOS (Europe), MSAS (Japan), and GAGAN (India) satellite corrections. Users receive real-time, 30-cm/1-foot positioning all day long, Geneq said.

The SXBlue II GNSS is targeted at GPS/GIS mapping professionals in industries such as forestry, utility, agriculture, and other natural resource industries in addition to local, state, and federal government users.

Geneq will be showing the SXBlue II GNSS at the Esri International User Conference July 24-26 in San Diego, California, booth #1203.
