Orbital Planes, Nightmares, Pioneers Good morning, Dr. Langley, I have a seven-year-old drawing of GPS satellites in their orbital planes that I found (can’t recall where) some years ago, either on a website or from a colleague who attended some GPS forum. Would you know of a site where I can find current information on GPS satellite locations, which ones... read more

Kickstarter Comes to GPS; Plus, Jammers and Field Technology Conference

September 4, 2013By

$2,000 for an RTK base and rover? Yes, it’s real. Well, at least it seems real. For $2,000, you can order an RTK base and rover set named Piksi, including radios.    It’s an intriguing opportunity, and might be the first brush stroke of the picture I’ve been painting (metaphorically speaking) for the past few years about inexpensive RTK receivers... read more
