SE100 GPS by Radiolink

RadioLink GPS For Radiolink Crossflight Flight Controller

The SE100, developed by RadioLink, is a widely used GPS module designed for seamless integration with Pixhawk and APM flight controllers via a plug-and-play cable. Beyond that, it is also compatible with many open-source systems such as PX4 and iNav flight controllers, making it highly versatile.

Unlike lower-cost alternatives that often use generic or imitation components, the SE100 is built with high-quality, genuine parts. It features a U-Blox M8N GPS chipset paired with a QMC5883L digital compass, ensuring precise and dependable performance. During testing, the module demonstrated impressive results by locking onto up to 20 satellites outdoors in under one minute, and it even achieved a 12-satellite lock indoors. The module also includes a convenient green LED indicator on top that flashes to signal when a stable GPS lock has been established, providing clear visual feedback.

Highlights and Features

• Superior Positioning Precision: Delivers approximately 50-centimeter positioning accuracy and can connect to around 20 satellites within seconds in open areas.

• Robust Signal Reception: The 2.5 dBi ceramic antenna design improves the ability to capture weak signals, even in environments with high interference, thanks to an advanced filtering system.

• Advanced Configuration: Equipped with a high-end u-blox UBX-M8030 (M8) chip supporting 72 channels, and Infineon’s MMIC BGA715L7 amplifier, offering enhanced performance beyond typical single GNSS solutions.

• Integrated High-Precision Compass: Includes a QMC5883L digital compass (I2C interface), which matches the accuracy of Honeywell’s HMC5983. Supports multiple satellite systems including GPS, GLONASS L10F, QZSS L1 C/A, and BeiDou B1, enabling dual-mode operation.

• Wide Compatibility: Fully supports Radiolink Pixhawk flight controllers and measures 1.89 × 1.6 × 0.59 inches, making it an excellent choice for DIY drones, quadcopters, multicopters, RC vehicles, and similar applications.
