ASR-8 Microwave Rotary Joint with Mode S capability and maintenance free Roll-Rings

ASR-8 Upgraded with Mode S Capability and Roll-Rings

Military radar systems such as SPS-48, SPS-67v1, SPS-67v3, SPN-43, ASR-8, SPN-35, TPS-75 and others are regularly repaired and refurbished by Diamond. Quick turnaround, competitive pricing and strong customer service continues to propel the growth of this business. Diamond maintains a dedicated group focused solely on ensuring repairs and refurbishments are completed with strict adherence to quality standards and are completed in a timely manner. With the recent addition of CST modeling, even the most challenging units can be repaired and improved.

An example of this expanded capacity is an ASR-8 five channel rotary joint which Diamond completely disassembled and restored but also improved with an additional L-Band module to provide Mode S compliance and a maintenance-free Roll-Ring® assembly to replace the maintenance prone slip ring.

Diamond also offers the unique ability to supply Roll-Rings®, a maintenance-free slip ring alternative, for use in lower frequency and power rotary transfer applications for radar systems including the US Navy’s SPS-48E long range radar system. Recently, the Federal Aviation Administration selected Diamond, based on best value, to replace all of the 43 Terminal Doppler Weather Radar slip rings with Roll-Rings®.
