LAPLander
 | This article needs to be updated. (September 2011) |
LAPLander (short for a light airbag-protected lander) is a prototype of a space probe primarily intended for measurements in the ionosphere. The prototype aims to evaluate the flight characteristics, e.g. air braking, of a flight from the border of space. Furthermore, the impact protection and recovery systems will be evaluated.[1] As the name says, the recovery system is based on airbags, that serve both deceleration and impact protection.[2] The future version of LAPLander will make it possible to do multi-point measurements, which will be of great help in the research of the complex processes within the ionosphere that contributes to auroras and disturbances in satellite communication.
Rexus flight
[edit]Laplander is selected for the REXUS/BEXUS program [3] and was launched on a sounding rocket flight from Esrange Space Center (outside Kiruna) in March 2010. The rocket is unguided, spin-stabilized, and powered by an Improved Orion motor, which is capable to bring the payload to an apogee of 100 km,[4] which is the border to space.[5] The event is sponsored by the Swedish National Space Agency (SNSA) and the German Space Agency (DLR), in cooperation with the European Space Agency (ESA).
Flight characteristics
[edit]To reconstruct the flight, LAPLander will record the following parameters:
- Three-axis acceleration
- Three-axis rotation rate
- Three-component magnetic field
- Temperature (for various parts of the payload)
- Raw GPS data
The latter is provided a cooperation with Cornell University, New York, United States. The device to be used is a novel miniature GPS, that in contrast to a common GPS can determine the attitude. This is made by measuring the phase difference from the GPS signal between two antennas.[2]
Development
[edit]The development of LAPlander started in 2008 and took place at the Alfvén Laboratory, Royal Institute of Technology in Stockholm.
