Hemisphere GPS Adds Smart Antennas

Hemisphere GPS introduced the new A220 and A221 smart antennas at the ION GNSS 2009 Conference in Savannah, Georgia in September. The antennas deliver centimeter-level positioning accuracy for precise guidance, machine control and survey applications. They feature Hemisphere’s Eclipse™ dual frequency receiver and antenna technology and optional radio modem, and support RTK, SBAS and OmniSTAR¨ HP/XP corrections.

The A220 features LED status indicators for power, GPS, and DGPS. The A221 additionally features a built in menu system and four-line LCD display, making it easy to monitor and configure as an RTK base station. Dual-serial, USB, CAN, and pulse output options enable the A220 and A221 to interface with many external devices. Multiple mounting options make both models easy to install and easily transferred between locations, vehicles, or machines.

“Hemisphere GPS is proud to unveil the newest Eclipse-based products in the A220 and A221 smart antennas at this year’s ION GNSS conference,” said Dr. Mohamed Abousalem, vice president, Marketing and Business Development for Hemisphere GPS. “These latest additions to our line … offer an affordable, dual frequency GPS solution …”

The antennas feature fast start-up, reacquisition, and output rates for the best signal for visual guidance and automated steering applications. They are compatible with CORS and other RTK reference networks where open architecture formats such as RTCM v3 and CMR/CMR+ messages are provided. They also offer Hemisphere GPS’s SBAS satellite ranging technology that increases the total number of satellites in view for greater RTK speed and reliability.
