Product Information
Product Name: Four-Element Anti-Jam Antenna
Product Model: DY-GGBR020P00E
Applicable Frequency Bands: BDS B1, GPS L1, GLONASS L1
Product Use:
Covering BDS B1, GPS L1, GLONASS L1 frequency bands, this product is widely used in military communication equipment such as command vehicles and ground vehicles, particularly suitable for applications with special requirements for anti-interference. This antenna array is used in conjunction with an anti-interference satellite receiver to provide navigation and positioning services in environments with strong interference.
Product Description:
l The antenna array consists of 4 anti-interference units for BDS B1, GPS L1, and GLONASS L1;
l Receives satellite signals from GPS-L1, BDS-B1, Glonass-L1, and Galileo-E1;
l Can suppress various types of interference, such as harmonics, swept-frequency, pulse, white noise, frequency modulation, amplitude modulation, and phase modulation, across broadband and narrowband spectrums targeting GPS-L1, BDS-B1, and Glonass-L1 frequency bands;
l Features functionality for configuration, query, and retention of operational parameters;
l Supports software online upgrade.

Interface Protocol
PROTOCOL FORMAT
The message format of UBX protocol is as follows:
Frame header (2-byte) CLASS ID MESSAGE ID (2-byte) Message length (2-byte) PAYLOAD checksum (2-byte)
Frame header: \consists of two bytes, namely 0xB5 0x62
Following the frame header is a byte of CLASS ID and MESSAGE ID information.
Message length: consists of two bytes, indicating the length of the PAYLOAD message sent later, and the byte order is little endian.
PAYLOAD: Output GPS information
Check digit: Two bytes of checksum, CK_A, CK_B
Data output frame definition
UBX-NAV-PVT (0x01 0x07)
The message combines position, velocity and time solutions, including precision numbers. The protocol output valid information is as follows:
