12.8 Installing an Antenna
Make sure the satellite signal strength is greater than 30db, when using a GNSS simulator for testing.
Read the following guidelines before installing your antenna.
- The S9501‐28SMT supports various types of receiver frequency types, including GPS L1C/A, GLONASS L1OF, BeiDou B1, and Galileo E1B/C.
- The minimum sensitivity of the receiver frequency (RF) is ‐166dBm.
- The S9501‐28SMT supports both passive and active GNSS antennas, and will automatically detect which type of antenna is installed.
- If the received signal strength is lower than 30db, the GNSS receiver will fail to produce accurate location estimates.
To optimize antenna performance, it is highly recommended to choose a roof or top floor that is free from any signal blockage or obstruction.
Read the following guidelines before installing an active antenna:
- When an active antenna is installed, the S9501‐28SMT can supply up to 5V DC/150mA on the GNSS port.
- If any GNSS amplifier, DC‐blocked or cascaded splitter is inserted, the GNSS detection function might be affected, resulting in GNSS satellite clock errors.
- We recommend that you use an active antenna equipped with 50 ohm impedance matching, 5V DC power supply capable, max. NF 1.5dB and 35~42dB internal LNA gain to get a strong enough signal strength in various weather conditions.
- To prevent damages caused by power surges or lightning strikes, ensure a surge protector is attached to the GNSS antenna.
