Sunday, 12 October 1997, we ( Roberto Ferrari and Enrico Falconelli )
have received our first nice image of Seastar satellite. The receiver
was tuned on the frequency 1702.5 MHz. The hardware was absolutely the same
that we use for Noaa HRPT, nothing was changed on the Noaa95 HRPT card. Beside,
the software Noaa95 was rewritten to receive and decode correctly the 8 channels
of the new satellite.
The orbit altitude is 705 km, each spectral band image is 1285+3 pixell width
and contain a scan width at Equator of 2800 km. Resolution is the same as
HRPT, each pixel ratio is square 1,1 km x 1,1 km on the ground.

Once you have received an image, our SeaStar97 software allow you to add different
channels and re-build an RGB color image as you like.

WARNING !!! |
SeaWiFS began encrypting the L-band |
### SeaStar 97 software output File Notation ###
SEASnnn_.RAW = 8 bit file multiplexed (the 8 MSbit as received)
After SPLIT function: nnn (image number) will be the same
SEASnnnA.RAW = 1st SeaStar Channel
SEASnnnB.RAW = 2nd SeaStar Channel
SEASnnnC.RAW = 3rd SeaStar Channel
SEASnnnD.RAW = 4th SeaStar Channel
SEASnnnE.RAW = 5th SeaStar Channel
SEASnnnF.RAW = 6th SeaStar Channel
SEASnnnG.RAW = 7th SeaStar Channel
SEASnnnH.RAW = 8th SeaStar Channel
By pressing CTRL+J a JPG file will be created and named SEASnnn.JPG
By pressing CTRL+P after split function (while
the 8 channels are displayed)
a PCX image wiil be created and named
SEASnnn.PCX
!!! Remember that NO hardware upgrades will be
necessary if
you already have the Noaa95 card !!!
