AggieSat4 deployment from ISS

UK astronaut Tim Peake KG5BVI preparing AggieSat4 for deployment

The deployment activities scheduled for Friday, January 29, 2016 include
capturing CYCLOPS with the JEM Remote Manipulator System, maneuvering
CYCLOPS to the deployment location, and final deployment of AggieSat4 from
CYCLOPS

An example of the deployment mechanism can be seen below.

There are four switches, embedded on the CYCLOPS EAF, that inhibit AGS4
from turning. The first event that will occur after deployment will be the
release of these inhibits. Once these inhibits are removed, the Electronic
Power System (EPS) starts and initiates a 10 minute timer. After the timer
ends the Command and Data Handling System starts and initiates a checkout
of every system on AGS4. When complete, AGS4 will begin sending a signal to
Earth with its Low Data Rate (LDR) radio, indicating that it is alive and
well. The team expects to start receiving signals from AGS4 on Friday
evening.

This animation shows how the Cyclops Deployment System launches satellites
in the 50 to 100 kg class from the International Space Station.

Handheld radios were presented to Sandringham School students

On Monday, JanuaryÂ* 26, 2016, Tony Wiltshire, M0TNY/ZB2TY from Martin
Lynch & Sons Ltd and Mark Haynes, M0DXR from Kenwood UK visited
Sandringham School in St Albans.

A presentation and demonstration was made to Polly, M6POG, Emma, M6GJQ and
Jessica, M6LPJ, the school’s newly licenced amateurs who previously had
made the initial contact with Tim Peake GB1SS aboard the ISS.

The girls had placed orders for Kenwood’s TH-K20E VHF handies with ML&S and
have been looking forward to being active on the bands with their own
equipment. ML&S hope the demonstration will get them the air very soon and
they also thank headmaster Alan Gray, G4DJX, for his hospitality and wish
Sandringham School Radio Hams the best for the future!

Rumour has it that 15 more students from the school will be taking their
licence exams as a result of the interest from the ISS contact.
