EVK-F9P-01 - User guide 4.3.8 LED On the front panel of the EVK unit, there is a single blue LED with the following functionality: Description Solid blue The device is powered on with no GNSS fix. The LED flashes one pulse per second during a GNSS fix. -
Page 13: Measuring Current
EVK-F9P-01 - User guide 5 Measuring current At start-up, the receiver starts in acquisition state to search for available satellites and to download GNSS orbital data, i.e., ephemeris and almanac. Once the data has been downloaded, the receiver enters the tracking state. In continuous operation, the receiver typically remains in the tracking state once entering it. -
Page 14: Rtk Setup
EVK-F9P-01 - User guide 6 RTK setup To achieve accurate RTK performance, the receiver needs a constant stream of correction data, which can be obtained from correction data providers via NTRIP or MQTT protocols. Application software is needed to fetch the data from the provider's server and send it to the receiver through serial ports. -

Page 26: Common Evaluation Pitfalls
EVK-F9P-01 - User guide 12 Common evaluation pitfalls • A parameter may have the same name but a different definition. GNSS receivers may have a similar size, price, and power consumption, but can still have different functionalities (e.g., no support for passive antennas, different temperature range). Also, the definitions of hot, warm, and cold start times may differ between suppliers. -
