Before there was GPS there was Loran-C. Raise Your Hand if You Worked with Loran-C. I used it for Timing on Quite a Bit of My Equipment.

Trust me, when I was Army ROTC, I did that too with the West Point cadets in the orienteering range up there....

WPN-5 (SPN-38) For some oddball reason we actually had the submarine version of this on my first ship, USS Claud Jones (DE-1033). Never worked properly, so I was sent to a month long C school on Ford Island. Finally find out why when the OPS boss tasked me with doing an inventory of all electronic gear assigned to the ship. On day three I went up the main mast and crawled out the yardarm to check the serial number of the antenna coupler. That's when I discovered that the shipyard had run a cable from the radio room up the mast and out the yardarm, but somehow had completely forgotten to actually splice it into the coupler......there it was, dangling free. A day later I was on my way to Mare Island for Nuclear Power School, class 68-4.

That's nifty...I'd very nearly gone Navy nuc per 6 yr enlisted, if USAF OTS had said no a 2nd time, I likely would've...I'd known a guy who's been a OIS grad and nuc pwr instructor in grad school, also....

PO1 William "Chip" Nagel my first trip to the Antarctic we used a SATNAV system that had a computer that took up a 10 x 20 room, with the best A/C on board. We would have to wait for a satellite pass, the dot matrix printer would spit out the Doppler’s. We would then check the accuracy of the fix, if it was a large error radius, we would look at the individual Doppler strings, and remove ones that had errors. To be honest I could get a better fix, faster with celestial. The year was 1977.
The next year our SATNAV shrunk to the size of a toaster oven, and the computer gave us the fixes and DR’s.
But I still enjoy breaking out my frankensextant and going old school. My sextant was built from 5 broken sextants, it is a Navy Mark II Thru V.
