The u-blox M9 standard precision GNSSplatform, which delivers meter-level accuracy, succeeds the well-known u-blox M8 product range. u-blox M9 receivers support concurrent reception of four GNSS.The high number of visible satellites allows the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as deep urban canyons. u-blox M9 receivers detect jamming and spoofing events and report them to the host, which allows the system to react to such events. Advanced filtering algorithms mitigate the impact of RF interference and jamming, thus enabling the product to operate as intended. The receiver also provides higher navigation rate and improved security features compared to previous u-blox GNSS generations. The NEO-M9N module is available in the 12.2 x 16.0 mm NEO form factor LCC package.
