CONCENTRATION OF RISK [Abstract]
CONCENTRATION OF RISK	NOTE 9 - CONCENTRATION OF RISK Because the Company sells into markets dominated by a few large service providers, a significant percentage of consolidated revenues and consolidated accounts receivable relate to a small number of customers. One customer of the Company's Satellite business unit accounted for 15% and 20% of consolidated revenues for the quarters ended August 31, 2014 and 2013, respectively, and accounted for 17% and 22% of consolidated revenues for the respective six-month periods then ended. This customer accounted for 13% and 15% of consolidated net accounts receivable at August 31, 2014 and February 28, 2014, respectively. A substantial portion of the Company's inventory is purchased from one supplier which functions as an independent foreign procurement agent and contract manufacturer. This supplier accounted for 60% and 64% of Company's total inventory purchases in the six months ended August 31, 2014 and 2013, respectively. As of August 31, 2014, this supplier accounted for 59% of the Company's total accounts payable. Some of the Company's components, assemblies and electronic manufacturing services are purchased from sole source suppliers.
