Nothlit Posted June 30, 2002 Share Posted June 30, 2002 I'm traveling to Puerto Rico next week on a mission trip, and while we're there we are going to be visiting the Arecibo radio observatory (you know, the humongous dish-in-the-ground from Contact and other various movies, and the source of SETI@home data). I would like to be able to plug the coordinates into my GPSr in advance just as a little diversion to be able to know and tell other people I'll be traveling with how close we are, how long it will take, etc, during the drive from where we're staying. If anyone here has ever visited Arecibo and marked it as a waypoint, or knows where to find the coordinates online, I would greatly appreciate it! Quote Link to comment

+mrp Posted June 30, 2002 Share Posted June 30, 2002 Picked off a NAPP photo, this is the coordinates I get from ExpertGPS (for the center of the dish): N 18d 20.653' W 66d 45.156' -- Mitch Quote Link to comment
Nothlit Posted June 30, 2002 Author Share Posted June 30, 2002 Thanks guys, I'll let you know when I get back how accurate these are. Quote Link to comment
Magellin Posted July 3, 2002 Share Posted July 3, 2002 Nice find "Pneumatic", I dont know who would be exactly correct on this. I do know that the #'s I posted are directly from the Cebo WebSite, and they dont say if that is the exact center of the dish or the final point for the RF reception (which could be at any point below the dish itself N/S - E/W ) (the image above shows that the true center is off from the reflectors LNB? by several feet if not by the tens) Also, I notice that if using a SAT image that the image in view is very rarely dead nuts over head on the object, so in doing so I dont think that mapping S/W will compensate for this and you would get a Deviation on the true Cords. Nice job on the find anyhow Eye, Ham, We, Todd, Did Sofa, King, We, Todd, Did Quote Link to comment
