Manpack vs. Flyaway vs. Auto-Deploy: How to Choose a Rapid-Deploy Satellite Terminal for Field and Emergency Operations

A wildfire crew crosses into a valley with no cell coverage and no power grid. Within minutes, incident command needs voice, mapping, and live data moving again. The terminal they carried in decides whether that happens in five minutes or fifty. Rapid-deploy satellite terminals exist to close that gap. They come in three different forms, and the wrong pick slows a team down when speed matters most. This guide helps field and emergency leaders weigh the trade-offs that count. Then it matches a terminal class to the mission. It leads with the decision, not the spec sheet.

Quick answer

• Manpack: smallest and lightest, carried and set up by one person on foot. Fastest to deploy, smallest antenna, so throughput is more modest. Built for forward teams and individual operators.
• Flyaway: packs into transit cases for air, land, or sea. Larger antenna and higher throughput than a manpack. A strong balance of portability and performance for a fixed site at an incident.
• Auto-deploy: vehicle-mounted systems that point themselves. They keep a link live on the move or lock on the moment a vehicle stops. Built for convoys and mobile command.
• Choose on the mission, not the brochure. Weigh setup time, weight, durability, GNSS resilience, power, and throughput against how your team actually deploys.
• The terminal is only half the decision. Managed service, support, and network design decide whether it performs when it matters.

Defining the three categories

Manpack: carried in, online on foot

A manpack is the smallest class. One person carries it and sets it up by hand. The antenna is small, so throughput stays more modest than a larger terminal. In exchange, it deploys fast and reaches places a vehicle cannot. The Intellian OW7MP Manpack is one example. It weighs under 9 kilograms, fits a standard rucksack, and uses one-touch network acquisition. It suits forward teams, lone operators, and any mission that moves on foot.  See Galaxy’s Intellian OW7MP Manpack for the Canadian configuration.

Flyaway: cased performance for a fixed site

A flyaway packs into one or more transit cases and travels by air, vehicle, or boat. Its larger antenna delivers higher throughput than a manpack. That makes it a good fit for a fixed setup at an incident base. Galaxy’s Scout Elite is a quick-deploy kit in this class. A team opens the case, mounts the antenna to the lid, and gets online in minutes. No specialist needs to be on site.

Auto-deploy: connectivity on the move or on the pause

Auto-deploy terminals mount on a vehicle and point themselves. Two modes matter here. COTM (Communications-On-The-Move) holds a link live while the vehicle drives. COTP (Communications-On-The-Pause) locks on automatically once it stops. Galaxy’s Mobile Commercial Network (MCN), built around flat-panel antennas, fits convoys and mobile command. The operator presses a button, not a compass.

The comparison framework and what actually matters

Setup time and pointing

Setup time is the first thing to weigh. A manpack with one-touch acquisition can be online in a few minutes, run by a single operator. A larger flyaway takes longer to assemble and aim, though auto-acquire antennas shorten that. Auto-deploy systems lock on at the press of a button, or stay connected while moving. Match the setup to who deploys it and under what pressure.

Weight and portability

Weight decides how the kit travels. A manpack under 9 kilograms rides in a rucksack and moves on foot. A flyaway packs into a wheeled or carried case for transport. Auto-deploy gear mounts to a vehicle and stays there. Ask one question: does someone carry this in, or does it ride?

Durability: MIL-STD-810H and IP67

MIL-STD-810H is the US Department of Defense standard for environmental testing. It checks how gear holds up against shock, vibration, drops, dust, rain, humidity, and temperature swings. It is not a single pass-or-fail badge. Makers test against the conditions a product will actually meet. So ask which methods a maker tested the terminal against. A bare claim of the standard tells you less. IP67 describes sealing against dust and water, defined by the international standard IEC 60529. The first digit, 6, means dust-tight. The second, 7, means the unit survives immersion in one metre of water for 30 minutes. That covers blowing grit and heavy rain. Immersion and high-pressure spray are separate tests, so a pressure-wash rating needs its own figure.

GNSS resilience in contested environments

GNSS (Global Navigation Satellite System) covers GPS and its equivalents. Auto-pointing terminals often use it to find the satellite and hold the link. In contested or remote areas, attackers can target that signal. Jamming drowns the signal and denies a fix. Spoofing feeds the receiver a false position, which is harder to spot. Ask the supplier a direct question. Can the terminal acquire without a clean GPS fix? Can it fall back to a manual point, or draw on multi-constellation and inertial backup? In northern and border operations, that answer is part of mission planning.

Power and battery

Battery runtime sets how long a team stays online between charges. Look for hot-swap batteries so the link never drops during a change. Vehicle power and solar stretch a deployment further. For a multi-day pop-up post, power planning counts as much as the antenna.

Throughput, latency, and the network

Throughput and latency depend on the antenna and the network behind it. Galaxy’s deployable kit runs on Eutelsat OneWeb, a Low Earth Orbit (LEO) network of around 600 satellites at 1,200 kilometres. Because those satellites fly in near-polar orbits, coverage runs strongest at high latitudes. That suits remote and northern Canadian operations. Latency sits near 70 milliseconds, close to terrestrial broadband, so voice and video hold up. Older L-band systems such as BGAN still serve as low-rate backup. A LEO link carries far more data for the same case.

Side-by-side comparison

Match the terminal to the mission

The right class follows from how a team moves and what it needs on arrival.

• Wildfire response: a flyaway at the incident base for command throughput, with manpacks pushed out to forward crews.
• Search and rescue (SAR): a manpack, because the team moves on foot into terrain a vehicle cannot reach.
• Pop-up command post: a flyaway for a fixed site, or an auto-deploy vehicle when command relocates often.
• Remote exploration or industry: a flyaway for base camp, a manpack for survey crews working away from it.
• Tactical and defence convoys: auto-deploy COTM, so the link stays up while units are on the move.

Beyond the hardware

Hardware only gets a team part of the way. Service, support, and network design decide whether the link holds when it matters. A LEO terminal still needs a managed plan, active monitoring, and a help desk in your time zone. Galaxy runs Canadian network operations centres around the clock, with sovereignty and managed support that remote operators expect. For high-stakes deployments, multi-path design, such as LEO paired with LTE, keeps a site online when one path drops.

FAQ

What is the difference between a manpack and a flyaway satellite terminal? 

One person carries and sets up a manpack on foot, with a small antenna and modest throughput. A flyaway packs into transit cases, uses a larger antenna, and delivers higher throughput for a fixed site.

How fast can one person set up a rapid-deploy terminal? 

A manpack with one-touch acquisition can be online in a few minutes. A cased flyaway takes a bit longer to assemble and point. Auto-deploy vehicle systems lock on at the press of a button.

What do MIL-STD-810H and IP67 actually mean for field durability? 

MIL-STD-810H is a US defence standard for environmental testing across shock, vibration, dust, rain, and temperature. IP67 means the unit is dust-tight and survives immersion in one metre of water for 30 minutes.

Do portable satellite terminals still work if GPS or GNSS is jammed? 

It depends on the design. Some terminals can acquire without a clean GPS fix, fall back to a manual point, or use multi-constellation and inertial backup. Ask the supplier how the terminal behaves in a degraded GNSS environment.

How much does a portable satellite terminal cost? 

Cost depends on antenna size, ruggedization, the data plan, and the managed-service level. A manpack costs less than a vehicle auto-deploy system. Over a deployment’s life, the plan and support contract often outweigh the unit price.

Which terminal is best for wildfire, SAR, or a mobile command post? 

Wildfire response usually pairs a flyaway base with manpacks for forward crews. SAR favours a manpack for foot mobility. A mobile command post leans on a flyaway, or an auto-deploy vehicle when it moves often.

Choosing your terminal

The choice comes down to how a team moves and what it needs once it arrives. Carry-in work points to a manpack. A fixed incident site favours a flyaway. Vehicles and convoys call for auto-deploy. Weigh setup time, weight, durability, GNSS resilience, power, and throughput against the real mission. Then confirm the service and network behind the hardware.
