But nothing came up in the patent search and the patent was awarded. His comment was that NASA might already be using a similar method. I had a chat with a scientist with Lina Space who actually owns some working cubesats currently operating in space supplying the information the the website. An app for a cell phone where GPS is down. The Coast Guard instructors want to see the electronic version where you make a manual measurement and plug into the program. This is where I was hoping you may come is. But the patent covers an electronic version as well. Currently the Patent is for the method and the manual astronomical device. The Naval guy said he will wait to see the Coast Guard assessment. The US Coast Guard seemed quite enthusiastic and quite surprised at the demonstration and asked me to give a detailed course to three head instructors with the thought of using this as a back up. That is pending because he is in England.

The Celestial Navigation instructor Gavin Lowe contacted his counterpart in the Royal Navy and wanted him to see what I have. He told me in all his years of Celestial Navigation, He had never heard of someone being able to tell longitude by making one star angle measurement without the use of the horizon.

I was given an appointment with the celestial navigation instructor at the Naval academy to give a demonstration. Once i develop a more accurate magnified optical divece i expect the accuracy to close approach reality. I must tell that Stellar navigation is quite different and quite accurate, developed for simplicity but the accuracy is near perfect but limited by my crude measuring device limits me to a +/- 0.1 degree which is close enough for emergency situations.
