1.1 Overview
The NEO-M9N module is built on the robust u-blox M9 GNSS chip, which provides exceptional
sensitivity and acquisition times for all L1 GNSS systems. The u-blox M9 standard precision GNSS
platform, which delivers meter-level accuracy, succeeds the well-known u-blox M8 product range.
The receiver also provides higher navigation rate and improved security features compared to
previous u-blox GNSS generations.
u-blox M9 receivers support 4 GNSS concurrent reception. The high number of visible satellites
allows the receiver to select the best signals. This maximizes the position accuracy, in particular
under challenging conditions like 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, and can allow the product to operate normally.
The NEO-M9N module is available in the NEO form factor LCC package.
