-
- ** UoSAT-OSCAR-9 **
-
- Current information suggests that UoSAT-OSCAR-9 re-entered the earth's
- atmosphere and burned up on the morning of Friday 13th October, after over 8
- years of operation. The last telemetry received in the UK was at 22:00 GMT on
- Thursday 12th October. The University of Surrey Command Station would be
- interested in receiving any telemetry taken after this time.
-
- ** UoSAT-D and -E Status **
-
- Two weeks ago, Arianespace postponed the launch of the rocket which is to
- carry SPOT-2, UoSATs-D and -E and the four Microsats into orbit. Early this
- week, UoSAT and AMSAT teams were formally notified that the new launch date is
- 19 January, 1990; the launch campaign will start some six weeks earlier, at
- the end of November.
-
- The launch delay will allow for more thorough testing of UoSAT-D and -E. This
- began on 29 Sept., when engineers from the European Space Agency Technical
- Center (ESTEC) came to perform final check-out of the Transputer Data
- Processing Experiment (TDPE) and its interface to the UoSAT-E CCD camera.
- These tests demonstrated the potential complexity and flexibility of the
- UoSAT-D/E onboard data handling system: Groundstation software was used to
- load TDPE programs as "blocks" to the standard UoSAT FORTH DIARY running on
- the 1802 On-Board Computer (OBC). The OBC then loaded these programs to the
- TDPE using the Transputers' built-in serial bootloaders using the UoSAT Data
- Sharing (DASH) bus. The TDPE then commanded the CCD camera to take a picture,
- the picture was transferred from the camera to TDPE at 5 Megabits/Second, and
- finally the TDPE downloaded the image at 9600 bits/sec. to the "groundstation"
- using a simple asynchronous packet format.
-
- The optics and the electronics of the UoSAT-E CCD camera were designed by
- engineers at UoSAT. The design is expected to provide Earth imaging with a
- resolution of approximately 2.7 kilometres and an image size of 740 x 960 km.
- The image is 386 pixels X 244 pixels with 8-bits of grey scale per pixel.
- Images will be transmitted on the UoSAT-E downlink to all radio amateurs,
- probably using AX.25 packet radio (generated by yet another on-board computer,
- a CMOS Z80).
-
- The mandatory flight-acceptance vibration tests were conducted this week back
- at the Royal Aerospace Establishment, and both satellites passed without
- hitch. UoSAT-D and -E are now in the clean room at the University of Surrey,
- where they will undergo nearly two months of operational tests, and provide
- testing grounds for the PACSAT and experimental software which is now under
- development at Surrey.

- First off, I responded directly to the original poster in a similar manner
- but from a different perspective, I'm an EC for the city of Milpitas here
- in Santa Clara county.
-
- John's statment about most of the real emergency traffic being handled on
- VHF is accurate. There is also a REAL balancing act about accepting
- third party Health&Welfare(H&W) traffic. The situation THIS TIME was
- that there were a large number of HF operators with working phones
- in the local area who could accept H&W traffic as was apparently the
- same case in the Mexico quake. This wan't the case in the Armenian
- quake, etc, and there still is THOUSANDS of peices of traffic that
- are being held by a certain ham that have yet to be delivered to Armenia!
-
- Moral of the story is be responsible! Don't promise what you can't deliver,
- and simply use common sense! If you hear lotsa different stations in the
- effected area accepting H&W traffic then go for it. If you hear a couple
- stations on the air and all they are passing is messages like "we need
- generators," or "send the National Guard" don't break in with your H&W
- traffic because the have more important things to handle!
-
- The people here who are accepting H&W traffic aren't really interfereing
- with the important stuff at hand, if they try we just tell them to
- go handle it themselves because we're to busy.
-
- Hope that clarifies the situations.

- No offense, OM, but most of us in 6 land _DO USE_ the 53MHz freqs for R/C
- because of the simple fact that the QRP nature of R/C transmitters tends to
- not disturb VHF Television Channel 2. Now I know that in NEWINGTON, CONN
- this is of no great concern, since they don't use TV Ch 2, but here it's a
- matter of survival! The ARRL 6 meter band plan is badly out of tune...look
- at the band plans that SMIRK (HQ for which is in 5 land, I believe..) or
- the Southern California Six Meter Club have offered. They put the LOW POWER
- device operation at the top of the band, and repeaters a bit lower; for
- this very reason. 50.5 - 51 is used for simplex around here.
