The one's at geostationary orbit are the GEOS birds and use S-band communications. The other ones are POES and are the ones that transmit on VHF. The POES are in a polar orbit ~530 miles up. There are currently three that provide APT. NOAA 12,17 and 18. There are two passes over a given point per day. The Hamtronics works great with a 5/8 wave 2 meter antenna. Just a few noise bands occasionally. I had an Eggbeater on the boat but it is too big and found the 5/8 wave to work almost as good. krj I wonder if the scanners on the 1600 Mhz band will pick up the other birds and if the software will decode it? the Ham guys have been getting these images from both the POES and GEobirds for years. Just do a google on NOAA Sat Spec's, and you can get all the Downlink Freqs, and coding types for each catagory of Birds.... |
