33 The offer of the MUT We are ready to test both the receivers and the software's We can help to solve some technical problems We can give the opportunity to verify the features of the receivers We can give an absolute certainty that receivers work correctly We posses the possibility to test how the receivers would work in i specified signal environment specially in jamming conditions WARSAW

34 Conclusion The modern laboratories need to cooperate with private partner The staff of the MUT posses high professional qualification and knowledge! The Avionics laboratory at the MUT is the only one /at this time/ to cooperate with JPO GPS to supply Poland in equipment to completely test the SAASM receivers /we meet the secret requirements, too/ WARSAW
