Les radiosondes M10 fournissent un excellent GPS (TRIMBLE 65530-00 Copernicus II) qui peut être reconditionné pour servir dans nos projets de ballon-sondes lâchés par des radio amateurs.
La première étape consiste à chasser ce type de radiosonde, ce qui n'est pas toujours évident.
Une fois la RS M10 récupérée, commence un travail de précision qui consiste à conditionner le circuit
pour l'utiliser en GPS presque "gratuit".
En principe, la M10 devrait finir sa vie dans une poubelle alors ce serait dommage de ne pas profiter de cette
merveille technologique.
La carte sera laissée telle qu'elle, elle sera débarrassée du support de piles et de la languette des capteurs.
Nous ne jetterons pas ces deux éléments qui seront eux aussi examinés ultérieurement.
Avant de faire une description complète des opérations, de la méthode et du matériel nécessaire, ainsi que
des résultats, je vous présente quelques photos de la deuxième étape :
!!! attendre les explications et conseils avant de vous lancer !!!
Les broches sont décalées pour faciliter le soudage. Elles seront remises en place à la fin.
Carte munie d'un bornier à picots, pour brancher un câble de longueur adaptée vers la carte microcontrôleur. Voir si la sortie nécessite une adaptation avec un MAX3232. (3,3 V to 5 V RS232).
Les essais restent à faire, à bientôt pour les résultats, commentaires, questions bienvenues sur le blog

GPS (PRESQUE) GRATUIT pour équiper les BALLONS-SONDES
SUCCESSFUL ARISS CONTACT IN DLR SCHOOL BRAUNSCHWEIG, GERMANY
SUCCESSFUL ARISS CONTACT IN DLR SCHOOL BRAUNSCHWEIG, GERMANY
Friday July 11, 2014 at 09:37 UTC, which is 11:37 local time, DLR School Lab, Braunschweig, Germany established a ARISS contacts with ESA
astronaut Alexander Gerst KF5ONO, onboard the International Space Station. This was a direct contact performed by Amateur radio ground station DN1DLR, located at school.
The German Aerospace Center (DLR) is one of Europe's largest and most modern research institutions. Here is where the aircraft of the future are being developed and pilots trained, rocket engines tested and images of distant planets analyzed. In addition, over 7,700 DLR staff members are investigating next-generation high-speed trains, environmentally responsible methods of generating energy, and much more...
DLR_School_Lab in Braunschweig investigates many topics related to transportation: whether on the road, rails, or in the air. In various experiments, school classes can acquaint themselves with the research topics being studied at the science institutes at DLR Braunschweig.
Mentor Francesco De Paolis IKØWGF proposed to the radio coordinators Mr. Michael Przybilla, DD2MIC and Mr. Niels Holger Siegmund DH1AL the direct contact supported by Telebridge Station IK1SLD and this was accepted. About 150 students, parents, visitors and media attended the event at contact site.
Contact was established at 09:37 UTC, which is 11:37 CEST local time, with DPØISS. Astronaut Alexander Gerst KF5ONO answered 13 questions by students. Signals from the ISS was loud and clear during all ISS pass.
NDR Television, 3 radio broadcaster, local media and 5 newspapers covered the event.
Here two tv reports on NDR:
