An article in the May 2012 edition of the free publication Microwave Journal shows that all of 1240-1300 MHz except for two narrow gaps will be used by global navigation satellite systems (GNSS).
The article by Rachid El Assir, Rohde & Schwarz, conatin a chart that graphically illustrates where the GNSS systems will operate in 1240-1300 MHz band.
A gap of about 3 MHz occurs at 1240 and one of about a MHz at 1259 MHz.
Masat-1, the First Hungarian Satellite made history again when it captured the first satellite space photographs on 8 March 2012 This first photo shows the southern section of the African continent. The next photos were made of Australia and Antarctica, in a quality and quantity unprecedented in the CubeSat realm.
The Flight Model of Masat-1
The on-board camera of Masat-1 has a mass of about two Euro coins. The maximal resolution is 640×480 pixels. A width of 1 pixel corresponds to a distance of 1 to 10 kilometres on the photos recorded.
The flawless operation of the passive attitude control system made it possible to capture photographs ahead of schedule, but with this passive system only the Southern Hemisphere of the Earth may be targeted by the camera. As the first month of the mission passed, almost every mission objective was fulfilled. The flawless run of the satellite opens a new scientific and technological horizon for experiments which we plan to perform in the coming months.
There is an increasing demand for Eath observation satellites worldwide both from the public and the private sector, as such spacecraft can capture on-demand, high resolution, up to date images of a specific area of the Earth’s surface. The captured images might be used for disaster relief operations,weather forecast services, crop yield estimation and tracking of agricultural operations, civil transport and cartography applications and also defence purposes.
As part of the ESA Education programme, seven CubeSats designed and built by European universities were placed into orbit by Europe’s new Vega launch vehicle on 13th February 2012.

What happens when rocket scientists get together in their spare time?
Michael Clive builds rockets during the day and Makerspaces at night. And this is no ordinary Makerspace, it’s in the “Silicon Valley of Space”..also known as Mojave, California. Find out how Michael gained support for this unique water hole in the desert and some unique challenges he faces.
STRaND-2, a twin nanosatellite mission from SSTL and the University of Surrey to test a novel in-orbit docking system using a gridded Lidar system based on the Microsoft Xbox Kinect games-controller technology.
Similar in design to STRaND-1, the identical twin satellites will each measure 30cm (3 unit Cubesat) in length, and utilise components from the Xbox Kinect games controller to scan the local area and provide the satellites with spatial awareness on all three axes – thus allowing them to dock.
The STRaND team sees the relatively low cost nanosatellites as intelligent “space building blocks” that could be stacked together and reconfigured to build larger modular spacecraft.

STRaND stands for Surrey Training, Research and Nanosatellite Demonstration and the programme is intended to be a long-term arrangement between the space company SSTL and academic researchers at the Surrey Space Centre (SSC), with STRaND-1 the first of a long line of STRaND nanosatellites.
The SSTL employees involved with the STRaND programme are volunteers. It is a condition of the programme that volunteers from SSTL and SSC use their own, free time for STRaND activities (such as lunches and breaks). The project has no budget for staff so is entirely dependent on volunteers.
