  • Excellent RF interference mitigation
  • Trimble Lassen SKII form factor
  • Replacement product for NLC-SKII-CP2V2

The NLC-SKII-M9N is a Trimble Lassen SKII form factor (mechanically and electrically compatible*) based on the robust u-blox NEO-M9N 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 NLC-SKII-M9N supports concurrent reception of four GNSS. The high number of visible satellites enables the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as in deep urban canyons. NEO-M9N detects jamming and spoofing events and reports them to the host, so that the system can react to such events. Advanced filtering algorithms mitigate the impact of RF interference and jamming, thus enabling the product to operate as intended.

 A SAW filter combined with an LNA in the RF path is integrated in the NLC-SKII-M9N module. This setup allows normal operation even under strong RF interferences, for example when a cellular modem is co-located with NLC-SKII-M9N.
