The program can easily detect and fix the TLE preliminary data errors
for working in satellite programs after launching the satellite in orbit
The original version of the program released before launching Fox-1D
works in Windows-7 and higher. Version that works in Windows XP is now
added. The program name for Win-XP changes to TLEdoctor.
Both programs can be downloaded at http://oscar.ok2gz.eu/fox1d.php

Hi folks,
AO73/FUNcube is now in amateur mode for the weekend with the transponder on!
Please see below for all FUNcube mission info
73s Graham G3VZV and the FUNcube team.
++++++++++++++++++++++++++++++++++
FUNcube frequencies and other details
++++++++++++++++++++++++++++++++++
AO-73 FUNcube-1
The transponder is normally operational only when the satellite is in
eclipse, ie the solar panels are NOT being illuminated. During weekends
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.
When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power. During holidays,
eg Christmas, New Year, Easter, etc, the transponder maybe activated for
extended periods. Watch AMSAT-BB for announcements which are usually made on
Friday evenings (UTC)
The nominal transponder frequencies are:
Uplink: 435.150 - 435.130 MHz LSB (Inverting)
Downlink: 145.950 - 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK
(The passband may be up to 15kHz higher depending on on-board temps. Lower
temperatures give higher freqs!)
FUNcube-2 (aka FUNcube on UKube)
The FUNcube-2 sub-system continues to operate autonomously and, almost
continuously, in amateur mode. The transponder is operational and the
telemetry downlink is functioning with about 70mW output. The FUNcube-1
Dashboard does not correctly display the telemetry but it does correctly
decode the data and uploads it to the FUNcube Data Warehouse from where it
can be examined. Most of the real time data channels are operational and
these include battery voltages, temperatures and ADCS data coming via the
main On Board Computer (OBC).
The transponder is interrupted for a few seconds every 2 minutes when the
other transmitter sends its CW beacon and, occasionally, for a few seconds
when the main OBC reboots (approx seven times each orbit).
The nominal transponder frequencies are:
Uplink: 435.080 - 435.060 MHz LSB (Inverting)
Downlink: 145.930 - 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK
(The passband may be up to 10kHz higher depending on on-board temps. Low
temperatures give higher freqs!)
EO79 FUNcube-3
Due to power budget constraints the transponder cannot be operational 24/7
and an orbit specific schedule has been developed. The transponder will
commence operation 27 minutes after the spacecraft enters sunlight and will
stay on for a period of 25 minutes. This schedule may be modified in future
months as a result of experience.
The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB
Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula…
EO88/Nayif-1/FUNcube-5
EO88 is presently operating in autonomous mode. The transponder is
operational when the satellite is in eclipse, ie the solar panels are NOT
being illuminated.
When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power.
The transponder frequencies are:
Uplink: 435.045 – 435.015 MHz LSB (inverting)
Downlink: 145.960-145.990 MHz USB
Telemetry Tx: 145.940MHz
All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very
grateful for the assistance given by Innovative Solution In Space Bv, The
Netherlands.

Hi All,Just to confirm that AO73 is now in continuous education mode with the high power telemetry. Amateur mode may be expected to resume on Thursday morning(UTC)73GrahamG3VZV
Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

Same here, beginning a week or so back. Investigating, but so far nothing
determined. Using WIN7 64-bit, and wondering if there was something in the
recent updates.

<Hello Amsat-ers
<

<
<I am using an Yaesu 5500 rotator controlled by a Lab jack under Satpc32
<v8.1. Intermittently the rotator stall under computer control. The LED on
<the lab jack indicate a signal to control the rotator to move but no
<movement. Terminating Satpc32 the rotator works normal. Suggestions??

Still looking for a Yaesu G550 elevation rotor .. If anyone has one in good working condition and wants to sell it, please email me Thank you JACK KC7MG good in qrz.com
The Chinese microsats LongJiang 1 & 2 have arrived at the Moon.
On 2018-05-25 between 14:00 and 15:00 UTC they are expected to pass
the Moon at a distance of about 300 km. At that time they should
perform a braking maneuver so that they can enter a high elliptical
300 x 9000 km orbit around the Moon. The planned orbit inclination
is unknown.
Unfortunately there is virtually no information on these satellites
coming from China. It is not clear if LJ 1 is recovered. Telemetry is
being received from the S band downlink of LJ 2 at 2275.22 MHz.
All other information, including recent orbital data, is missing.
Note that the usual satellite tracking programs and regular TLE
data can not be used for tracking satellites near the Moon. You
really need specific deep space tracking software and orbital
elements. TLE sets for the LongJiangs that were published earlier
have no value at all now that these satellites are in the vicinity of
the Moon. Again I would like to refer to my web page on this
subject:
