Satellite arcing experiment


150921: test data with 327 rcvr
151018-151021: satellite data
160929-160930: satellite data
170405-170408: satellite data, pulsar data
170303: 327 sidelobe loss vs angular offset.


   s3043 wants to see if they can see arcing on satellite solar panels using AO and the 327,430  and 47 MHz receivers. Test data was taken on 150921. The actual run on the satellites occurred 18oct15 through 21oct15.

150921: fast dump spectra using the 327 receiver.

     On 21sep15 i took some fast dump data using the 327 receiver. The setup was:

Processing the data:

18oct15 - 21oct15: satellite data

yymmdd  (AST = UTC - 4)

 Setups used:

Description of daily observations

 Acquiring the data:

    Two sets of simultaneous data were taken:

Processing the data:

    From the radiometer equation we have that:

Satellite beam:


Decide which broad band spikes to keep.

 Looking at the data

Exporting files:

    Each days data are stored under a separate subdirectory (the directory names are the AST dates when data was taken):

03mar17 looking at objects in 327 sidelobes

    Most geostationary satellites are below our minimum dec range (0deg).
One idea to look farther south, is to put the object in a sidelobe of a the receiver.
