FUNcube-1 AO-73 Upload Trend

FUNcube-1 AO-73 Upload Trend

The FUNcube team were interested to know the trend of the number of uploads to the warehouse since launch, we thought we would share our findings.

We have been consistently getting more than 5000 raw packets per day and the trend is increasing, thanks folks!

The plan is to issue this on a monthly basis.

Videos: Understanding orbits

Understanding Orbits

Understanding orbits can be called the key to understanding satellites. These videos by Nanosatisfi cover many facts about orbits.

This second video about orbits covers the math involved in calculating a pure circular orbit.

A Dnepr carrying the 310 kg Spanish imaging minisatellite Deimos-2 along with 20 other satellites is expected to launch from Dombarovsky near Yasny in April/May. The satellites will be deployed in a 600 km orbit.

UK CubeSat Programme in New Electronics

New Electronics has a feature on the UK CubeSat programme and UKube-1 which it says should be launched from Kazakhstan on March 27, 2014.

Caroline Harper is a programme manager at the UK Space Agency and one programme that comes under her wing is UKube-1.

CubeSats can also have a role in education, as Harper pointed out. “We have a payload called FUNCube, which will allow kids in schools to download real housekeeping data from the spacecraft almost in real time and to do their own experiments on that data. We hope that will encourage interest in STEM subjects.”

FUNcube was developed entirely by volunteers at the amateur radio organisation AMSAT-UK. TOPCAT, meanwhile, is a payload that will measure the regions of space just beyond the Earth’s atmosphere – the ionosphere and plasmasphere – in order to help GPS users by monitoring and subsequently reacting to variable space weather conditions that adversely affect the Global Positioning System. The payload will consist of a specialised dual frequency GPS receiver that is suitable for operation in the space environment. The development has been led by a postgraduate at the University of Bath, with support from Chronos Technology, RAL and MSSL.

In addition to the educational telemetry beacon the FUNcube boards on UKube-1 will also provide a 435/145 MHz linear transponder for SSB/CW communications.

UKube-1 communications subsystem:
• Telemetry downlink 145.840 MHz
• FUNcube subsystem beacon 145.915 MHz 1200 bps BPSK
• 400 mW inverting linear transponder for SSB and CW
– 435.080 -435.060 MHz Uplink
– 145.930 -145.950 MHz Downlink
• 2401.0 MHz S Band Downlink
• 437.425-437.525 MHz UKSEDS myPocketQub Downlink

FUNcube-1 realtime data available as .csv download

FUNcube Data Warehouse

FUNcube Data Warehouse

The FUNcube Data Warehouse is now producing .csv files containing Realtime data channels for the AO-73 CubeSat.

The data is produced every hour, on the hour and contains 3000 rows, starting 250 minutes before the last record in the database.

As we do not have worldwide coverage, there will be missing segments of data. To overcome this, we fill the data with the last value before the gap.

All records are have an associated ‘satellite time’ this is based on the known activation time of the satellite and offset calculated from the sequence number and frame type. The satellite is currently 3 hours 50 minutes ahead of the data server time.

Please visit the Real Time Data page and click on the link in the descriptive text.

Deorbitsail CubeSat

Students and researchers at the Surrey Space Centre (SSC) in the University of Surrey, Guilford, are developing the 3U CubeSat Deorbitsail. It is planned to launch on a Dnepr rocket into a 600 km Low Earth Orbit (LEO).

The aims of the mission are:

(1) Deploy a large (5-by-5-metre) square Kapton sail.

(2) Deorbitsail is equipped with 3-axis-stabilizing attitude determination and control system. A novel capability of this system is pointing via Centre-Of-Mass / Centre-Of-Pressure (COM/COP) offset.

(3) The satellite will deorbit much more quickly than otherwise due to its deployable sail. Satellite pointing will be optimized by the attitude control system for maximum drag.

(4) The satellite will provide beacons which radio amateurs will be able to receive. The ISIS UHF/VHF radio will provide a 9600 bps BPSK downlink on 145.975 MHz.
