Abstract:
The project focuses on characterizing the microwave
background at stratospheric altitude in the frequency band between
45 and 75GHz. With emerging technologies pushing the useable bands
higher, it becomes important to understand possible interferences in
higher frequency bands. The secondary goal of this experiment is the
testing for a possible future cryogenic HASP mission designed
specifically to detect the Cosmological Microwave Background (CMB).
MRE II will use the latest passive microwave reception technology on
the smallest scale ever attempted to capture and analyze these
waves.
The McNeese MRE II team consists of five senior engineering
students, and all have past engineering experience in various
fields; two have prior experience in the LaACES program (MRE, 2006).
The team is structured into a group dynamic much like that seen in
industry. Every member is accountable for their own budget and
technical area, but they are encouraged to interact in a team
environment to exchange ideas and get the job done.
The MRE II module will utilize HASP’s 30 VDC power supply to
power thermal control and processing equipment.
A DB9 connector will be used to transmit real-time telemetry
via HASP’s telemetry system using the provided RS-232 link. Data
will be stored on board, via high capacity data storage. To address
possible problems in the sampling rate, given the high frequency of
the original data band, we are going to use a heterodyne system.
