NEO-M9N - Integration manual
2 System description
2.1 Overview
The NEO-M9N GNSS receiver features the u-blox M9 standard precision GNSS platform , and
provides exceptional sensitivity and acquisition times for all L1 GNSS systems. u-blox M9 receivers
are available in different variants to serve automotive and industrial tracking applications, such as
navigation, telematics and UAVs.
The u-blox M9 standard precision GNSS platform, 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.
2.2 Architecture
