En fantastisk liten satellit med namnet STRaND-1 som kommer att använda en smarttelefon som omborddator.

Den kommer även att ha ett litet propulsionsystem vilket man aldrig trodde kunde vara möjligt för ett antal år sedan.

Det går framåt!

Ivo Klinkert, PA1IVO, har skrivit en mycket bra artikel med fina bilder om hans portabla satellitstation. Se följande hemsida:

2013 ser ut att börja bra med en fin satellit från England på väg upp i rymden,

AMSAT-NA meddelar att de har en ny pre-amp i sitt sortiment. Den är för VHF/UHF banden och byggd runt en MAR 7-krets. Överskotten går till AMSAT Fox-satelliterna och den kostar ca. 50 US$.
AMSAT-NA is pleased to announce an inexpensive, broadband VHF/UHF/WX
satellite receive-only preamplifier.

Key features:

Ready to operate–not a kit! Fully assembled, tested, and installed
in a metal enclosure with female BNC connectors on input and output.

It is based on the MAR 7 device, and covers 100 MHz to 500 MHz.
This includes the137 MHz WX, 2M, and 70cm satellite bands.

Operates from +9-15V DC (a fresh 9V battery works great!).  Perfect
for portable operations using dual band hand-held Yagis like the
ARROW, Cheap Yagi, etc.  Just put it inline on the correct receive
band for operations in either mode U/V or V/U. You won’t believe what
you’ve been missing!

Includes low power (about 5W) protection diode on the input for
accidental transmissions into the input. (This preamp is not RF
switched. It must be protected from inadvertent repeated or high
power transmission RF using a relay or diplexer.)

Full details and schematic can be found in the November/December
2012 AMSAT Journal article by Mark Spencer, WA8SME, or downloaded
from the item in the Hardware section of the AMSAT Store:

http://store.amsat.org/catalog/

The assembled and tested kit is priced at $50 USD plus shipping.

Proceeds from the sale of this item will help fund the AMSAT Fox
Family of satellites!  This equipment was developed as part of the ARRL Education and
Technology Program.

Lite nyheter från Nordamerika där det är nya friska ideer på gång för att få upp nya satelliter.

AMSAT Submits a Second NASA ELaNa Proposal

The official name of the project is “RadFxSat” and it is a joint
project with the Institute for Space and Defense Electronics (ISDE)
at Vanderbilt University. AMSAT is providing the satellite bus
(Fox-1B) and ISDE is providing the experiment payload. The primary
mission is to advance the state of the art in understanding the
effects of space radiation on electronic components.

This is the first AMSAT satellite with science as the primary mis-
sion. This is very exciting as it potentially opens up new launch
opportunities. Since the data downlink and power required by the
experiment are modest, we expect to be able to operate the science
payload and the ham radio transponder simultaneously.

The satellite hardware design is the same as Fox-1 but there will
be substantial AMSAT work in systems engineering, project manage-
ment, software development, satellite construction and testing.

We requested a launch in the 2nd half of 2014 to a 650 km sun-synch-
ronous orbit which is the same as we requested for Fox-1. As in our
previous proposal, we also noted that the mission requirements can
be met over a wide range of orbits. The key elements are the need
for a high enough apogee to provide significant exposure to space
radiation and a minimum 10 year orbit lifetime.

While there can be no guarantee that our proposal will be accepted
by NASA, we believe that in its 241 pages (!) we have made a strong
case.

NASA is expected to announce the accepted proposals at the end of
January 2013.

Angående Nordkoreas satellit; Jag fick tag i lite keplerelement som är rätt osäkra men det  är ändå värt ett försök. Frekvensen ska vara runt 470 MHz
