Subject: Geographic Locator for Autostar Sent: Friday, July 20, 2007 14:03:49 From: Esther y Fernando (firstname.lastname@example.org) GPS and DIGITAL COMPASS FOR AUTOSTAR 497 Pardon by my English since it is not too good. The system that I present to you is relatively simple. It consists of a small microprocessor in charge of: 1. - To read plots NMEA of a GPS, and to extract the Hour information, Length, Latitude and date. 2. - To read the information of a digital compass with resolution of tenth of degree. 3. - To display in LCD, all this information. 4. - To update, via RS232, the internal information of the Autostar (Date, Hour, Length and Latitude). 5. - To help to correctly position the tripod of the Telescope on the basis of the information coming from the digital compass. Way of operation: Once connected the feeding of the device, display begins to show the information of the GPS and the digital compass We oriented the tripod towards the north and when information GPS is correct, LED GPS OK, we pressed button UPDATE AUTOSTAR and in seconds, the Autostar is formed perfectly.next, we can begin our session of observation Originally, this thought for my telescope ETX-90 AT, but is easily updatable for other types of telescopes. All the materials used in the construction of this device, are recycled or bought to low price reason why the cost very it is not elevated. In the photos of down you can see the device mounted in the telescope and working. At the moment I am working to add the reading of a digital inclinometer for a correct positioning of the telescope. If you want more information, or to do some suggestion to me, you can send an email to me a: email@example.com A greeting for all from Zaragoza, Spain EXPO 2008
