Operations & Maintenance Technician

NetCentric Technology LLC, a subsidiary of ASRC Federal, is seeking a full time Operations & Maintenance Technician in Fairbanks, AK.

Operational Specific:

Cortex, PTP, Matrix switches, 700MR receivers, 1620 Combiners, Front End Processor, IMUX, GDP Model 268 Bit Synchronizers, TSS 2000, MFRs, DFM antenna drive system, GSIF equipment, GOES TACTS system, Fiber optic transmitters and receivers, up and down converters, multi-couplers, level converters, and IOLAN communication server.

The following are minimum operational requirements for this position:

1. Have a good working knowledge of the 13M, 5M, 21M and 26M equipment, DATA flow Paths and equipment used.
2. Know what and where the proper tools and test equipment are for maintenance and repair.
3. Know what manuals and drawings to use and where to locate them.
4. Maintain equipment under their control in their area of responsibility.
5. Be able to recognize problems or failures and respond to them in an appropriate manner.
6. Monitor Pass setups and supports and resolve any anomalies noted.

1. 1. 1. Confirm schedules for all antenna supports
      2. Monitor equipment setup prior to AOS, communicate with appropriate control center and local CMD/TLM personnel.
      3. Start plots if required, monitor event page, Scopes, Spectrum analyzers, data strings, IMUX, antenna tracking, and command generator for proper operation during support.
      4. Keep the Lead informed of any equipment, communications, or software malfunctions.
      5. Troubleshoot and repair end items where appropriate.

1. Make sure all scheduled passes are scheduled on the appropriate systems.
2. Know how to setup the DATA BASES for different spacecraft. Test Equipment Operation:
3. Should know how to setup and use the following test equipment.

Spectrum analyzer, Oscilloscopes, Generators, Multi-meters, Power meters, Counters, Soldering Equipment.

1. Other duties as required.

Area specific equipment:

1. Should understand basic operation and how the following equipment fits into the flow of data from the satellite through antenna system to PACS.
2. Antenna systems, Bit synchs, Receivers, Combiners, Generators, Matrix switches, Up/Down converters, Frame synchs, and Timing equipment. Knowledge in electronic principles and theory.
3. RF fundamentals i.e., (dB, dBm, VSWR), Impedance, OHMS Law, modulation, etc.
4. Troubleshooting skills; Ability to trace data flow through circuits and isolate malfunctioning components.
5. Solder training, advanced solder techniques, Surface mount and ball grid soldering

Anomalous operation:

Able to isolate 13-Meter problems to antenna tracking or a RF. Some data/RF problems can be quickly cleared with a receiver, combiner, or bit synch reset. If the FEP or the stream has halted or the lMUX didn't go into record - You would normally go to a backup antenna if one is available and can be brought up in time to complete the pass. If it can't be fixed in a matter of seconds, we want to capture the data and fix the problem later. Let the Lead and support center know immediately if you notice a problem.

Requirements:

A minimum of five years of active electronic control systems knowledge; including maintenance on said systems. Technical school training or other formal training in electronics equipment operation and maintenance are a plus for prospective new employees.

College or other types of degrees may be submitted as experience when those degrees are centered on electronics technology or electronics engineering. The ability to effectively read circuit diagrams and blue prints is required along with the ability to trouble shoot to component level. Excellent soldering skills required in order the replace failed components.

Must also be able to operate and properly interpolate the results obtained from test equipment such as analog, digital and RF signal generators, spectrum

analyzers, digital and analog oscilloscopes, function generators, RF power meters, signal simulation equipment and fiber optic test equipment. Additional test equipment may vary depending on specific requirements.

Experience with work stations operating on the following platforms: Windows, VAX, VMS, LINUX, Unix, and Solaris.
