The HEPF GPS Logger is a telemetry sensor that provides fast and accurate real-time position detection. To achieve maximum precision and resolution, multiple navigation systems are used simultaneously. The integrated flash memory allows for the logging of all data. The logged data can be downloaded and analyzed on a computer using the free MAV Manager software.

Features:
• Compact size, high measurement accuracy.
• Large industrial memory for data recording.
• Next-generation GPS chipset supporting multiple satellite systems.
• 3-axis magnetometer/compass for external navigation purposes.
• Voltage measurement and logging.
• Automatic telemetry detection: Duplex EX, Hott, MSB, S.Bus2.
• Automatic time zone detection.
• Configuration via the transmitter.
• Firmware updates.

The GPS Logger app for JETI DC/DS transmitters can display the current position of the model on a graphical map background on the transmitter's display. It is possible to define multiple flight zones as well as no-fly zones, each with different shapes (circles, rectangles, and simple KML files are supported). You can also set an optional alarm for entering/exiting each zone.

For each zone, you can specify the following parameters:
Flight Zone/Restricted Zone: These types are marked by different colors and alarms. Minimum and maximum altitude of the zone: Represent vertical limits. The altitude refers to the starting position. Audio on entering/exiting: Set an audio alarm to know when the model has crossed the boundaries of the zone. Proximity warning: The alarm sounds when the model is at a short distance from the zone and moving toward it.
