Are Your MIlitary Communications Too Reliant On Satellites?

In March 2019, the US Air Force launched an advanced military communications satellite. This satellite significantly increases the bandwidth available for military communication. There’s just one problem: protecting satellites from natural and human-made disruption and attack is severe. What are your other options to reinforce military communications?

Knowing Your Communications Enemy Is Half The Battle

Before we start to solve the problem, we need to take a step back and understand what interferes with satellite communications. Until we define the limitations of satellite communication, you cannot plan when or how to address those disruptions.

1) Satellite Disruption Through Natural Means

Let’s start with the traditional challenge: natural disruption. You might imagine that outer space is an empty vacuum where nothing happens. There is plenty of natural activity happening all the time in space. For satellite users, solar flares are the most significant disruption. Researchers at the British Antarctic Survey found that existing protections for satellites are inadequate to protect them from solar winds.

“Electronic components on satellites are usually protected from electrostatic charges by encasing them in metal shielding. You would have to use about 2.5 mm of aluminum to reduce charging to safe levels — much more than is used at present.” – Professor Richard Horne, lead author of the study (Satellites more at risk from fast solar wind than a major space storm)

Theoretically, this risk could be mitigating by improving shielding or launching new satellites. However, such improvements are unlikely to occur in the short term. That’s why we will cover alternatives to satellite communication below.

2) Satellite Disruption Due To Technical Failure

Unlike ground-based communications, satellites are difficult to maintain. That’s a problem Earth’s orbit is filled with space debris. According to NASA’s Orbital Debris Program Office, there are over 20,000 orbital debris objects in Earth orbit larger than 10 cm. It just takes one small collision to damage a satellite’s capacity. Further, repairs and preventative maintenance are limited. Remember how long it took to fully repair the Hubble Space Telescope? It took multiple missions to correct the problem.

In a rapidly developing tactical situation, you cannot reasonably expect a last-minute repair mission for your satellites. If they are damaged by debris, you will be out of luck.

3) Attacks, Jamming And Human Disruption To Satellite Disruption

It’s no secret that military organizations depend on satellite communication. As a result, we see increased efforts to target and disrupt this vital element of military communication. For instance, consider India tested an anti-satellite weapon test in March 2019. This device would have the ability to attack satellites at an altitude of up to 300 KM. In addition to India, China and Russia are actively developing anti-satellite weapons, according to CNBC. One new Russian anti-satellite weapon is planned for completion by 2022, so you may have a few years to prepare for a new generation of threats to satellites.

Launching missiles, lasers, and other space-based attacks is not the only way to disrupt satellite communication. Traditional radio jamming in a local area can prevent ground forces from using satellites in a local area. Your ability to operate effectively may be significantly compromised by enemy action, so you need to get ready for those threats now.

The Solution To Satellite Communication Vulnerability

We recommend looking at military communications like an investment portfolio. You need a variety of assets in your portfolio to achieve your goals and reduce risk. You wouldn’t put all of your retirement savings into a single stock. Likewise, your military communication should not rely on a single point. To develop your communications portfolio, we recommend using the following steps.

Evaluate Satellite Communication Dependence

Assess your current communication systems and practices to see how many people would be impacted by a failure in satellites. Start by reviewing the direct impact: satellite phones and GPS devices. Next, look for examples of indirect dependence on satellite technology. For example, does your organization’s command and control facilities rely on satellites to coordinate operations?

Define The Impact of A Satellite Failure

Vague doom and gloom about failed satellite communications do not help you to take action. Instead, you need to spell out the consequences. Here are some specific areas to evaluate:

  • Navigation. Are you reliant on GPS for vehicles, ships, and other operations? Do your personnel have alternatives?
  • Speed and Throughput. If satellite communication failed, would your alternative systems like conventional radio have the bandwidth to keep up?
  • Coverage. Satellite systems are excellent at covering large areas. That capability may be difficult or too costly to replicate with other systems.

Inventory Your Alternative Communications Systems

Picture the worst-case scenario – your satellite communications are entirely offline for 24 hours or more. In that context, how will you operate? Cellular communications and radios are likely to be the right choice. For that option to work, a full inventory is needed. For example, how many of your bases have trained staff and fully operational equipment? Now that you have this list of equipment in place let’s put those capabilities to the test.

Verify Your Non-Satellite Capabilities With Exercises

Reviewing the literature on satellite communications, creating inventories, and other activities will only take you so far. To validate your assumptions, you need to go into the field with an exercise. You can either add “satellite disruption” to an existing exercise or create an entirely new exercise dedicated to it.

After the exercise is completed, use an after-action review to measure the impact of satellite failure. Specifically, look for comments on increased errors, operational delays, and travel problems.

Implement Communications Redundancies

Following the completion of a test exercise, you will see just how much you take satellite communication for granted. To act on that information, reevaluate your non-satellite options. For example, consider increasing your cellular communication capability. Consider using 4G LTE as an alternative. In 2013, the US Department of Defense started testing military LTE (i.e., avoid using civilian LTE infrastructure) in a test.  That test found transmission speeds up to 70 MB/s, which may be sufficient for many tactical communication scenarios.

Base Camp Connect

Base Camp Connect provides rapidly deployable communications to public safety agencies to help them bridge communication gaps in the field. BCC empowers Military and First Responders by proposing communications go-kit that are simple to use, portable, configurable, and that doesn't require training to operate them.
