NORAD numbers given but no TLE



… will we ever see keps ???


CP6 TLE swapped by NORAD


Colin, VK5HI: ... the CP6 keplerian data being issued for CP6 is definitely incorrect. I have been using the Day227 element set for Hawksat for the last week. Have not encountered any wild frequency excursions. Today I downloaded element sets for Days 233 & 234 and compared them against Day227_Hawksat, with a “simulator” program I have. The CP6 sets show up to 3 KHz deviation at TCA, whereas the Hawksat are just a few hundred Hertz.
I have just used the Day 234 Hawksat keplerian set on the most recent pass, with excellent tracking. The AOS & LOS also align well.
SpaceTrak gives an RCS of .774 for Hawksat and .0575 for CP6, so I cannot understand how they are getting them mixed up…

cp6_35004_23082009

cp6_35003_23082009

Colin, you gave me a good task for this evening, hihi. I tracked CP-6 with TLE OBJ 35004 ( this was the original CP6 TLE) at 1815 UTC.
For the second pass I used the TLE OBJ 35003 (the original HAWKSAT TLE) at 1905 UTC.
You can see the deviation in the first image and a nearly constant – and correct Doppler shift correction – in the second one.
I know it’s hard to determine this exactly because all my passes are low here I Germany. The first pass was 11 deg, the second one 19 deg elevation.

So I agree with you, Colin – fine job!

Alan, ZL2BX: Yes it has seemed obvious that something changed with the TLE’s. Before I
went away in June I had no particular problem but since coming back last week I have seen up to 5kHz offsets during the pass but using the “Hawksat”
TLE’s this reduced to a few Hz with about a 500 to 600Hz difference between Com A and Com B. All very interesting!


Encounters



 
 

As a service to the satellite operator community, the Center for Space Standards & Innovation (CSSI) offers SOCRATES-Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space. This service provides regular information on pending conjunctions on orbit over the coming week.

Twice each day, CSSI runs a list of all satellite payloads on orbit against a list of all objects on orbit using the catalog of all unclassified NORAD two-line element sets (TLEs) releasable to the public to look for satellite conjunctions over the next seven days. Here you can find a list with amateur-radio related satellites.

CelesTrak SOCRATES, predicts the following Orbital Conjunction Threats

EO-79 transponder ACTIVE


qb50p1_002
2E0SQL is calling CQ

Hi All,
Today, 25th of March 2016, the EO-79 transponder has been turned on for a prolonged period.

The FUNcube transponder subsystem on QB50p1 (EO-79) had been provided by AMSAT-UK and AMSAT-NL and is a similar subsystem as on FUNcube-1, but without the telemetry downlink circuitry.

The current software running on EO-79 does experience occasional reboots. When these reboots happen, the transponder is automatically turned off and will have to be turned back on by a command station.
The FUNcube team has selected a few command stations to do so, but be advised the transponder may be off.

TLEs:
AMSAT keps name: EO-79
Celestrak keps Name: QB50P1
Celestrak file: cubesat.txt
NORAD # 40025
COSPAR designator 2014-033-R

Frequencies:
Uplink: 435.035-435.065 MHz LSB
Downlink: 145.935-145.965 MHz USB

EO-79 has been set to only beacon the normal AX.25 beacon every 30 seconds instead of 10 seconds. The beacon frequency is 145.815MHz and consists of AX.25 frames on BPSK. more details about the downlink can be found on the ISIS HAM page at http://isispace.nl/HAM/qb50p.html

Just like FUNcube-1, the crystal oscillator circuits exhibit drift with temperature. This means manual tuning will probably work best.

Lastly, the commanding team availability will be limited over Easter, so please report the transponder being on or off on the status page of AMSAT: http://www.amsat.org/status/
It does not appear in the table, but it does in the reporting drop-down.

73 and have FUN

Dear friends,

firstly many thanks for your long-term support in collecting online telemetry for UWE-3 and QB50p1 over the last months.

The amount of incoming data is increasing very fast and so we (Jan, PE0SAT and me, DK3WN) decided to use a new – database based – approach.
This software can run in the background and alongside other decoders and/or AGW-OnlineKISS etc. The following satellites are supported: BISONSAT, BUGSAT, CUBEBUG-2, DEORBITSAIL, FIREBIRD-3, FIREBIRD-4, GRIFEX, MCUBED-2, O/OREOS, POLYITAN, QB50P1, QB50P2, STRAND-1, TIGRISAT, UNISAT-6, UWE-3, PHONESAT2.4, ZACUBE, XW-2A..2F

We decided to take these sats because they could be easily decoded by UH7ZO soundmodem software (1k2, 9k6, 19k2 – BPSK, AFSK, FSK). All received packets will be checked, automatically assigned to the correct NORAD ID and forwarded to Jan’s PE0SAT server (Total_HTTP/Total_HTTP_OK).
Packets from unsupported satellites will be not forwarded but counted (RX). Every packet will also be logged in the /log directory. So we have a kiss file backup for all incoming packets selected by their satellite name. You can use these kiss files with my telemetry decoders (file -> open serverlog) for further processing.

Jan is working on the database front-end. You can see here some statistics (packets per user, packets per satellite, last 10 received packets).
Additionally you can download all received packets – this may important for the cubesat teams (download requires authorization.)

So please feel free to test the forwarder software. If you have any comments or suggestions for improvements, let us know.

Please edit the online_conf.ini file with your correct callsign and coordinates.
Many thanks for your support !!!

Here can you dowload the software: http://www.dk3wn.info/files/tlm_forwarder.zip

EO-79 transponder activation


qb50p1_spectrum

Hi All,

Today, 21st of December 2015 at 1038 UTC, it is planned that the EO-79 transponder will be turned on for a prolonged period.

The FUNcube transponder subsystem on QB50p1 (EO-79) had been provided by AMSAT-UK and AMSAT-NL and is a similar subsystem as on FUNcube-1, but without the telemetry downlink circuitry.

The current software running on EO-79 does experience occasional reboots.
When these reboots happen, the transponder is automatically turned off and will have to be turned back on by a command station. The FUNcube team has selected a few command stations to do so, but be advised the transponder may be off.

TLEs:
AMSAT keps name: EO-79
Celestrak keps Name: QB50P1
Celestrak file: cubesat.txt
NORAD # 40025
COSPAR designator 2014-033-R

Frequencies:
*Uplink:* 435.035-435.065 MHz LSB
*Downlink:* 145.935-145.965 MHz USB

EO-79 has been set to only beacon the normal AX.25 beacon every 30 seconds instead of 10 seconds. The beacon frequency is 145.815MHz and consists of
AX.25 frames on BPSK. more details about the downlink can be found on the ISIS HAM page at http://isispace.nl/HAM/qb50p.html

We kindly request you to share your experiences with the BB so everyone can benefit from operating tips and tricks, as well as being up-to-date on the status.
We would also welcome any observation related to the transponder behaviour when the AX.25 beacon comes on.

Just like FUNcube-1, the crystal oscillator circuits exhibit drift with temperature. This means manual tuning will probably work best.

Lastly, the commanding team will not be available over Christmas, so the current activations are planned from today until Thursday 24th and from Monday 28th until Thursday 31st

73 and have FUN
Happy Holidays
