Mini GPS signal generator for development and testing systems

The Mini GPS signal generator is a highly integrated device designed for R&D and testing systems. It simultaneously supports multi-band GPS signal output, covering common navigation and positioning application needs. The product can simulate real satellite signal environments, supporting different frequencies, code types, and modulation methods to meet various scenarios such as receiver development, algorithm verification, and system integration. Through flexible configuration, users can quickly construct complex navigation signal combinations, significantly improving testing efficiency and result reliability.

1) Supports signal reception and simulated transmission at commonly used frequencies of the four major global navigation satellite systems;

2) Can perform navigation deception on drones that rely on satellite navigation and positioning systems, achieving objectives such as forced landing, driving away, prohibiting takeoff, and interfering with navigation satellite signals;

3) Supports external command control of arbitrary navigation signal combinations for transmission;

4) Supports setting arbitrary location coordinates (longitude, latitude, altitude) via external commands, and can also have built-in fixed coordinates;

5) Supports setting simulated parameters such as signal delay, motion speed, and acceleration via external commands;

6) Supports setting preset trajectories such as linear motion and circular motion via external commands;

7) Supports externally added motion trajectories; the board calculates and outputs the corresponding navigation satellite signals based on the input information;

8) Supports real-time ephemeris mode and permanent ephemeris mode;

9) Supports satellite navigation signal suppression and interference output;
10) Provides a network secondary development control interface;

The device features a built-in high-precision crystal oscillator temperature compensation calibration function, which automatically corrects frequency deviations under different temperature environments, ensuring long-term stability and accuracy of signal output. This function effectively reduces the impact of temperature changes on test results, enabling the device to maintain consistent performance in both laboratory and field environments, making it particularly suitable for high-precision positioning and time synchronization testing needs.

The Mini GPS signal generator comes with comprehensive online help documentation and technical support. Users can obtain quick start guides, configuration instructions, and frequently asked questions through the official website. Simultaneously, a professional technical team provides remote support and application consultation to help users efficiently solve various problems encountered during development and testing, shortening project cycles.

Before leaving the factory, the product undergoes rigorous environmental and reliability testing and verification, including high and low temperature, vibration, aging, and continuous operation tests, to ensure that the equipment remains stable and reliable under complex application conditions. These verification processes guarantee the consistent performance of the product in R&D, production line, and field testing, providing users with a reliable testing tool.
