MOS 25S Requirements: Qualifications and Skills

In order to become a MOS 25S, there are a few requirements you need to acquire:
Qualification
Applicants should have a high school diploma or be a GED graduate with experience as a civilian technician or operator/maintainer for satellite communication systems. There are no age restrictions to enlist into this MOS, but applicants must have been U.S. citizens.
ASVAB scores must be valid at the time of application to qualify for consideration. To be an Army Satellite Communication System Operator, applicants will undergo rigorous training, including the U.S. Army Signal School Basic Course for 10 weeks and Advanced Individual Training (AIT) for 18 weeks. A 117 score on the Electronics segment is required.
The course includes extensive simulations and hands-on experience operating satellite ground terminals and satellite communication systems. You’ll also learn how to install, configure, operate and maintain equipment; perform switching operations; provide customer service; take measurements; assemble mechanical devices; use power tools; read blueprints for the layout of parts needed for fabrication work.
Work under stress
Operators, maintainers, and repairmen of the MOS 25S are often faced with changing needs and unforeseen obstacles. They may be required to work under stressful conditions such as long hours or working weekends. This job requires operators to monitor software progress during live operations.
Thrive in a team environment
Operators will often work alone on some tasks but would also work in a team environment for the integration of future systems or more complex components that require coordination. Operators provide oversight on multiple technicians at once who are responsible for monitoring, implementing changes, resolving errors, troubleshooting coordination problems, and communicating with each other through walkie-talkies or cell phones.
The need for continual communication is essential to maintaining SATCOM’s operation. For instance, if the satellite system is experiencing errors, operators are required to break down the error code and determine how it can be corrected. Furthermore, systems must be programmed according to the system’s capabilities rather than following what was originally intended by developers.
However, programmers or maintainers may work independently if needed to address other issues. This job also requires operators to work with many other types of professionals such as electrical technicians, engineers, computer specialists, and software specialists in order to complete the mission effectively. Thus this job requires strong teamwork skills that allow operators to communicate with each other and other personnel on a regular basis in order to complete the mission effectively.
Job Responsibilities
A few main responsibilities are associated with MOS 25S, including satellite communications, quality control tests, paperwork, network operation, and preventive maintenance.
Satellite Communications

Satellite Communications (S.C.) is the provision of communications capabilities through the use of geostationary (satellite) earth-orbiting satellite systems. Army personnel must possess an Army Qualification Test that has earned entry into S.C. and then serve as an operator/maintenance to provide the high-level management of operations for satellite equipment. After understanding how S.C. works, they must be able to install, operate, maintain, and test this equipment in order to meet mission requirements.
The MOS 25S is responsible for providing satellite communications (SATCOM) services through point to point, point to multi-point, and broadcast. They plan, set up, operate, maintain and monitor Satellite Ground Equipment (SGD). SATCOM operators provide instructions to the SATCOM system concerning the transmission of information between two or more locations. These instructions are provided by them using Automated Terminal Information Service (ATIS) equipment which enables the operator to communicate with both terrestrial and satellite facilities. The ATIS equipment consists of VHF/FM equipment used in providing initial instructions to aircraft or ships, or ground stations upon request. They will also monitor data link messages which are sent between computers by way of radios via satellites. Operators are responsible for providing the essential command information between two or more points via satellite equipment.
Quality control tests

Quality control tests for MOS 25S are used to measure the performance of an item in use. This is typically done when an operation has begun or when there are insufficient parts available for a complete test. The quality control testing process specifies the types of tests which should be performed in order to assess whether or not an operation is being executed effectively.
The Quality control tests specified by MOS 25S include: Inspection, sample preparation, beam power measurements, checkerboard pattern generation, carrier lock-on/off measurements, as well as coupler sensitivity and signal power measurements. In the United States Army, quality control testing is used to measure the performance of a product in use. For example, a soldier may need to know how well the antenna on his radio works during certain conditions, such as on a cloudy day or when there is a lot of interference.
Two types of quality control tests for MOS 25S are system performance tests and subjective tests. System performance tests are used to assess the overall operation of an item during the performance of an operation. The purpose of these tests is to determine an item’s capability for its intended purpose. System performance tests check for failures, identifying whether or not there are any problems with the instrument so that corrective action can be taken before it malfunctions and causes damage. Subjective tests assess the condition or performance of an item based on human input. The purpose of these tests is to verify that a product meets acceptable criteria for its intended purpose. Subjective testing requires a trained technician who will use his or her knowledge and experience to evaluate whether or not the item is operating as it should be
System and Equipment Paperwork

The MOS 25S is responsible for preparing and filing records, data, reports, work requests, equipment transfers, etc. To complete this job duty, the MOS 25S will utilize the AFDD 13-8 to ensure all paperwork is filed correctly. Conduct network operations: The MOS 25S performs system testing using various test equipment plants to ensure the SCCS is operating properly. This includes conducting voice and data tests on satellite links. When an anomaly occurs, the MOS 25s must troubleshoot the problem to determine the cause of failure. They are also required to provide recommendations on how to correct problems discovered during testing.

Preventive Maintenance

It is a series of planned or unscheduled repairs that are done before the satellite communication system fails. A preventive maintenance schedule is developed by communication site personnel. Preventive Maintenance may be accomplished by the operator/maintainer on his/her own or under contract to a third-party contractor.
Preventive Maintenance Includes: Maintaining inventory on consumables and expendables, performing on-going preventive maintenance tasks, performing periodic inspections by qualifying personnel for satellite communication system operating positions, scheduling replacements of failed components, preparing for emergencies, including tests of communication equipment prior to use in field operations.
