AMATEUR SATELLITE TYPES Analogue FM Single Channel Analog Transponder -SSB/CW Digital Digital and Analog ISS
4
SATELLITE ORBITS Low Earth Orbit - LEO High Altitude Elliptical Orbit
5
LEO ORBIT - 1000 Kilometers Nominal
6
O High Elliptical Orbit

AMATEUR SATELLITES IN ORBIT OPERATIONAL - 16 SEMI OPERATIONAL - 11
8
OPERATIONAL SATELLITES 2 ANALOG + DIGITAL 8 ANALOG 6 DIGITAL ISS http://www.rac.ca/ariss.htm
9
ANALOG SATELLITES TRANSPONDER - 8 FM REPEATER - 2
10
SATELLITE MODES OPERATE CROSS BAND Up on one band - Down on another Analog operation FULL DUPLEX
11
TRANSPONDERS Receives and retransmits a frequency band eg. RS-12 mode K non inverting Rx 21.210 to 21.250 Tx 29.410 to 29.450 AO-40 mode U/S inverting Rx 435.550 to 435.800 TX 2401.475 to 2401.225

LEO ANALOG TRANSPONDER SATELLITES AO-7 2 m up / 10 m down 70 cm up / 2 m down RS-12 15 m up / 10 m down RS-13 15 m up / 2 m down RS-15 2 m up / 10 m down FO-20 2 m up / 70 cm down FO-29 2 m up / 70 cm down
14
HIGH ORBIT TRANSPONDER SATELLITES AO-10 70 cm up / 2 m down AO-40 2m or 70 cm or 23 cm up / 13 cm or 1.3 cm down
15
MY INTEREST HI ORBITERS LARGE FOOTPRINT WORK MOST OF WORLD ( not just W and VE) EASY TO RAGCHEW SEVERAL OPS GET INTO DISCUSSION ON THE SAME FREQUENCY SMALL DOPPLER AND ANT POINTING INCREMENTS
16
MY FAVOURITE AO-40
17
AO-40 VERY LARGE ELLIPTICAL ORBIT VERY LARGE FOOTPRINT ONE ORBIT TAKES 19 hrs 6 min CIRCLES AROUND EQUATOR www.amsat-dl.org/journal/adlj-p3d.htm
