A full-featured 10 Hz telemetry GPS with microSD memory card, TEK Vario, and accelerometer!

The new Version 3 replaces the GPS Logger 2 and remains fully compatible.

The new hardware offers:

• a new GPS module for better GPS reception even under difficult conditions
• further improved pressure sensors for even finer Vario resolution with lower noise
• a horizontally oriented TEK connector for easier installation, especially in tight fuselages

The GPS-Logger 3 is a full-featured GPS system specifically developed for the needs of the model-making sector.

It is extremely small and lightweight, yet offers outstanding features and capabilities.
With a recording rate of up to 10 Hz and the micro-SD memory card, recordings of almost any length with high-resolution detail are possible.

Telemetry via 2.4 GHz systems with a return channel is a standard feature of the GPS Logger 3 and is fully integrated.
In line with our philosophy of supporting as many systems as possible, the GPS Logger 3 also supports telemetry from:

• Jeti Duplex
• Multiplex M-Link
• Graupner HoTT
• Futaba
• JR DMSS
• FrSky
• Spectrum (via Spectrum adapter)
• PowerBox Core

The telemetry system used only needs to be specified once in the GPS-Logger 3 settings. This can be done either via our PC program "GPS-Converter" or using the UniDisplay. HoTT is selected by default.

The GPS-Logger 3 uses a built-in high-resolution pressure sensor to provide high-quality vario data via telemetry and, thanks to the integrated TEK connector, also allows the use of compensation nozzles. This results in a vario function that displays actual climb and descent very accurately, independent of "stick thermals."

For precise altitude measurement even when operating with a TEK nozzle, a second pressure sensor is built in, which provides accurate altitude data regardless of speed.

Information about in-flight loads is provided by the built-in 3-axis accelerometer. At each waypoint in the recording and also via telemetry, the acceleration along all three axes can be displayed here.

The new OLC competition format, the Online Contest, is also optimally supported by the GPS-Logger 3. The built-in noise sensor (ENL = engine noise level) provides data that automatically identifies engine runtime during climb. The IGC file required for the OLC is created directly on the memory card and digitally signed; no conversion software is needed.

The GPS-Logger 3 can also be used for another competition format, namely Soaringleague.
Soraingleague.net is a new website for easy online evaluation of gliding flights with any model. It doesn’t get any easier than this!

When operating with Multiplex M-Link, all data on the sensor bus is automatically logged by the GPS-Logger 3 and also written to the memory card > MSB data logger.

In addition to its own measurements, the GPS Logger 3 can also read the complete data from our UniLog 1 + 2 and UniSens-E live via a direct connection cable and write it to the memory card.

All measurement values from the GPS-Logger 3 can be viewed directly in real time via our UniDisplay. All settings and alarms can, of course, also be conveniently programmed via the display.

The data is displayed and analyzed in 3D in Google Earth^TM. To convert the data to the Google Earth^TM format, you only need our free "SM GPS Converter" software and the standard version of Google Earth^TM, which is also free.

Our GPS-Logger 3 is also supported by the well-known LogView software. Here, the GPS data can also be converted to the Google Earth™ format. In addition, the values can be displayed in standard graph or table format, and much more.

Based on Java and therefore suitable for Mac or Linux as well as Windows, the GNU DataExplorer is available for analyzing the data.

Whether for gliders, aerobatic planes, helicopters, HLGs, or slow flyers, the GPS Logger 3 can be used in virtually any application thanks to its low weight and compact size. Of course, the GPS Logger 3 isn’t just suitable for model aircraft. It can also be installed in RC boats, RC cars, and more.

And here’s what the GPS-Logger 3 can do:

• 10 Hz GPS, i.e., 10 measurements per second, providing
  particularly high data resolution
• microSD memory card:
  virtually unlimited recording and easy data retrieval
• Data is stored as plain text on the
  memory card Further processing possible with many programs
• High-resolution variometer with TEK connector
• Altitude measurement with a second pressure sensor featuring automatic zeroing after power-up
• Integrated 3-axis accelerometer up to ±16 g
• Direct creation of the IGC file for the Online Contest (OLC) With integrated engine noise sensor for ENL measurement
• Full telemetry support for Jeti Duplex, Multiplex M-Link, Graupner HoTT, Futaba, JR DMSS, FrSky, and Spektrum (via Spektrum adapter)
• Direct connection of UniLog 1 + 2 and UniSens-E possible for data logging (not during Futaba, JR DMSS, and FrSky operation)
• Recording of all data on the Multiplex sensor bus when operating with M-Link
• Connection for receiver signal to remotely control certain functions
• Recording of receiver battery voltage
• Power supply via receiver battery
• Internal backup battery for quick GPS startup
• Start of recording can be set based on various conditions
• Current status is indicated by three LEDs
• View measurement values live directly with our UniDisplay (not during Futaba, JR DMSS, and FrSky operation)
• Parameter settings possible via PC, UniDisplay, and telemetry
• Quick conversion of data into a 3D view with Google Earth™ using our free "SM GPS Converter" software.
  The program is available for free on our website www.sm-modellbau.de under the Software & Updates menu item.
• Support via the LogView software
  LogView is a very comprehensive yet easy-to-use analysis program for the PC that supports a wide variety of different measurement and charging devices from the model-making sector.
• Support via the GNU DataExplorer software
  The GNU DataExplorer is just as comprehensive as LogView and is compatible with Windows, Mac, and Linux.
• Free firmware updates are available via memory card (the firmware file is available online at www.sm-modellbau.de under the Software & Updates menu item)

• Can be used virtually anywhere thanks to its compact size and low weight
