Agenda
1) Motivation
2) What’s currently available on the market
3) What is APRS
4) Solutions based on APRS
5) OpenGlaide® Network architecture
6) Current status and plans
Motivation
 we are a group of glider pilots
 we like gliding and computing 
 Some of us are passionate radio-amators 
 Some of us have background from another similar
projects (Zarbrick)
 We would like to create a system that improves safety of
our sport and attracts attention to gliding
 It is fun 
Currently available tracking solutions
GSM/GPRS/SMS
Satellite
SOLUTION
EXAMPLE USAGE
CONS
GSM/GPRS/SMS
Variety of
competitions in
Lithuania, Australia
Slovakia (Previdza,
Nitra)
Simply do not work as expected if AGL > 300m
Spot: cannot program – sends a message every 10
min.
- Gaps in transmission, latency (SMS)
- Buffering, constant reconnection attempts = gaps in
transmission
Satellite trackers
GP w Chille, WAG
Yellowbrick (sat. Iridium) 2009
Expensive devices !
Expensive data transmission
Vmax < 180 km/h
APRS
APRS
Solutions based on APRS
-
Zarbrick (2008-2010, Poland GSS ZAR)
 build for competition, not suitable as permanent solution
 re-programmed APRS trackers used (TinyTrak3,
OpenTracker+)
 we used aviation frequency (~130Mhz) in place of 2m
 we used our own base receiver stations to cover
championship area
 synchronization of emitters required
 limited number of our emitters built
Zarbrick – onboard the glider
Zarbrick - base station @Skrzyczne
(Poland) - GP 2009
Solutions based on APRS
-
OpenGlide® (2012- France, Switzerland, Poland)
 no need to build own emitters – they are already there! (FLARM)
 no emission, just passive reception
 We use our own instance of APRS server & we use open APRS
protocol - everyone can get the data and build his/her own
visualization client
 Cheap! ( 1 station = ~50 eur)
 OpenGlide® for FLARM is like Flightradar24 for ADS-B

OpenGlide® - current status and plans
- currently installed receivers: Challes-les-Eaux (FR), Cluses
(FR), Grenoble(FR), Roannie(FR), Zar(PL), Rys(PL),
Birrefeld(CHF)
- reception up to 70 km*
- increase system coverage in Europe (especially in the Alps)
 new installation planed soon: Saleve (FR), Annecy (FR),
Mole (FR), Barcelonnette(FR)
-
Improve decoder performance to run in wide-band mode on
small low-power computers (cubieboard2)
- Anyone willing to join is very welcomed ! 
Thank you
