Hardware-in-the-loop (HIL) testing often requires replaying recorded GPS data. gps2udp can be configured to read from a file (emulating a serial device) and send the recorded NMEA log to multiple simulation nodes via UDP.
open_serial(port, baud) open_udp_socket(target_ip, target_port) while (running): data = read(serial_fd, 4096) sendto(udp_fd, data, len, 0, (target_ip, target_port)) if (multicast_mode): for each client in client_list: sendto(udp_fd, data, len, 0, client_addr) gps2udp
Its primary purpose is to decouple GPS hardware from GPS consumer applications, allowing multiple clients on the same network to receive real-time position, velocity, and time data without needing direct access to the physical GPS device. In telemetry, speed is often prioritized over guaranteed
In telemetry, speed is often prioritized over guaranteed delivery. UDP (User Datagram Protocol) is a "fire and forget" protocol. Unlike TCP, it does not require a three-way handshake, error checking, or retransmission of lost packets. While gps2udp is a generic concept, there are
While gps2udp is a generic concept, there are several real-world implementations:
