DRAFT SPECIFICATION 1 www.taoglas.com SPE-23-8-241-A The Taoglas Comet AA.250 is an active GNSS magnetic mount antenna for use across all major GNSS constellations, with the L-Band for correction services also added for optimizing GNSS systems. The antenna exhibits excellent gain and good radiation pattern stability leading to a reliable GPS fix in areas of weaker signal strength. These elements combine to ensure the best possible positional accuracy in both RTK and nonRTK systems. Typical applications include: - UAVs and Robotics - Autonomous Vehicles - High Accuracy Positioning - RTK Systems - Precision Agriculture The AA.250 provides excellent positional accuracy, this is due to outstanding signal to noise ratio(C/N0) and a low axial ratio, ensuring the antenna maintains stable when a location is required. With great 2DRMS and Fast time to first fix the AA.250 is the ideal antenna solution for Multiband GNSS RTK Systems as it performs very well, with stable gains and low axial ratio values across all major GNSS bands. The AA.250 includes dual stage LNA and front-end SAW filters to reduce out of band noise, such as from nearby cellular transceivers. It offers better protection from nearby radiated power surges and greatly reduces the probability of damaging your GNSS receiver from nearby transmissions. The AA.250 has 1 cable feed as the internal feeds are combined with a hybrid coupler and the antenna performance results are shown in the below sections. The cable and connector are fully customizable, subject to NRE and MOQ. For further information please contact your regional Taoglas customer support team.
