GPSmodul

GPSModul is a compact GPS receiver module designed to provide geographic position data by receiving signals from the Global Positioning System satellites. It typically includes a GNSS receiver, an RF antenna, and a host interface for data communication. These modules are built for easy integration in embedded systems, consumer devices, vehicles, and robotics projects. Depending on model, GPSModul may also support other satellite systems such as GLONASS, Galileo, or BeiDou, expanding satellite visibility and reliability.

Interfaces commonly include serial UART, I2C, SPI, or USB. Data is usually transmitted as NMEA sentences (for example GGA, RMC, GSV) or in binary formats such as UBX. Many modules provide a one‑pulse‑per‑second timing signal (PPS) for precise timekeeping and can be configured with command sets to adjust update rate, output sentences, and power modes.

Performance and power: Typical horizontal accuracy with GPS alone is about 2–5 meters; with augmentation and reliable sky view, 1–2 meters is achievable. TTFF (time to first fix) ranges from a few seconds to tens of seconds depending on cold/warm/hot starts and the amount of almanac data. Sensitivity around −160 dBm allows work in moderate indoor conditions near windows.

Power consumption varies by model but commonly ranges from tens of milliamperes in tracking mode to a few microamps in sleep. Supply voltages are usually 3.0–3.6 V or 3.3–5.0 V. Antenna considerations include active antennas with built‑in LNA or passive types; placement and shielding influence performance.

Applications include navigation, timing, asset tracking, drones, robotics, and wearable devices. Use of GPSModul requires an unobstructed sky view; performance degrades indoors or behind dense structures. Development often involves configuring baud rate, update frequency, supported constellations, and protocol, then parsing received position, velocity, and time data.
