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 22% and 18% of consolidated revenues for the quarters ended November 30, 2013 and 2012, respectively, and accounted for 22% of consolidated revenues in both of the nine-month periods then ended. This customer accounted for 17% and 14% of consolidated net accounts receivable at November 30, 2013 and February 28, 2013, respectively. A substantial portion of the Company's inventory is purchased from one supplier that functions as an independent foreign procurement agent and contract manufacturer. This supplier accounted for 65% and 52% of Company's total inventory purchases in the nine months ended November 30, 2013 and 2012, respectively. At November 30, 2013 and February 28, 2013, this supplier accounted for 60% and 63%, respectively, of the Company's total accounts payable. Some of the Company's components, assemblies and electronic manufacturing services are purchased from sole source suppliers.
