    I hadn't noticed the wide BPSK signal on about 20745MHz before.


    1.2m Prodelin 3122 az-el with one of:
    S: Helical feed, 0.8dB NF LNA, X: 1.2dB NF LNA, conical feed,
    Ku 12-18GHz: corrugated conical feed, 1.5dB NF LNA, Ku (Standard): SMW Q-PLL type C, Prodelin feed. Ku (Extended): 11.3GHz LO SMW & Prodelin Feed Ka: Gilat ex-ODU PLLs Gilat feeds, Ka 18-26.5GHz: Patriot feed, home made 4dB NF LNA, Ka DSN: Corrugated conical feed, home made 3dB NF Down-Converter

    1.5m IRTE, Polar mount with Octagon OSLO mod. C120, IRTE feed
    40km East of London, UK

    My circular left spectrum. Inclination -1.8° at scan time.

    Can´t see it...

    It's not very strong and may have been lost in the VSWR ripple. Try IQ Monitor with normalisation enabled. I've turned the gain up and added some filtering on this plot.

    SBIRS-Geo 2 (incl. 1.7°) is at 20.7°E now, has moved a little bit from 20.6°E a while ago.


    SBIRS-Geo 1 (incl. 1.8°) is at 66.2°E since 2019.


    SBIRS-Geo 5 (incl. 7.7°) is at about 8.6°E, and has just arrived here after a 5-month journey from testing location 145.5°W.

    Note the high inclination, maybe this is to detect infrared events (launches) a little bit further North?

    Just another circular left spectrum - no changes.

    -1,42°inclination at scan time.
