SparkFun Electronics has released the SparkPNT TX2, a quad-band GNSS rover that combines an IP67-rated aluminum enclosure with support for Galileo’s High Accuracy Service (HAS) and standard RTK correction workflows.
The receiver is built around the Quectel LG290P quad-band GNSS engine and supports multi-constellation tracking. Galileo HAS support provides sub-20 cm accuracy globally without subscription-based correction services, while RTK workflows via NTRIP or u-blox PointPerfect can achieve centimeter-level positioning.
Battery life is rated at 50-plus hours, positioning the TX2 for multi-day field campaigns without recharging. The unit connects to iOS and Android devices via Bluetooth and Wi-Fi, with compatibility reported for common GIS and data-collection applications.
A notable design choice is the open-source firmware, which gives users visibility into how positioning data is processed and allows for customization and third-party integration. SparkFun has positioned this as an alternative to closed GNSS ecosystems where firmware and processing pipelines are not user-accessible.
