#MYCROFT classified #DARPA satellite inspector that uses the #EAGLE platform as a mother-ship is departing 5S and I believe has been detected on S-band. I first noted short 'glitches' of a signal and then prolonged periods of wideband noise. 1/3

In the images above one can see periods of time when there's a rise in the noise level periodically throughout day. These periods are preceded by a fast moving carrier 'glitch'. The rectangle shows the area I zoom into. This behaviour is similar to #EAGLE as noted here. 2/3

#MYCROFT recently inspected #5S from close proximity and it and #EAGLE are now drifting 'rapidly' away. @M_R_Thomp noted that #MYCROFT is likely USA 287 based on official statements made before the inspection. airforcemag.com/afrl-dispatchi…

@M_R_Thomp The radio frequency for #MYCROFT and #EAGLE where obtained from ITU records.

@M_R_Thomp These are significant observations as it shows a mission using a largely suppressed carrier signal which makes it significantly more difficult to detect by amateurs (or others). Yet #EAGLE emits it's carrier... Begs the question what other missions use this technique...?
