Why GEO

The proven backbone of mission-critical communications

GEO satellite networks remain the foundation for critical operations worldwide, predictable coverage, stable performance and mature infrastructure that keeps working where terrestrial networks stop. And in a multi-orbit world, GEO VSAT is what guarantees performance: while LEO services share capacity among all users, GEO delivers committed bandwidth with contractual service levels, on its own, or as the assured layer in a hybrid GEO + LEO setup

Predictable
coverage

Established orbits and mature networks deliver stable performance across regional and global beams, with regulatory approvals in place across the markets you operate in

Guaranteed
performance

Dedicated bandwidth and committed information rates with clearly defined service levels (SLAs), throughput you can plan operations around, not best-effort speeds.

Three bands,
one partner

Ku, Ka and C-Band across leading operators, matched to your sites, routes and availability targets by our engineering team.

Fully
managed

Proactive network monitoring, service management and 24/7 technical support behind every deployment, one accountable partner from design to daily operations.

Frequency bands

Choose the band that fits your operation

Each band carries a different trade-off between throughput, coverage and weather resilience. Our engineers help you match the right band, or combination, to your requirements.

Ku-Band

The versatile workhorse

The most widely deployed VSAT technology worldwide, a proven balance of performance, coverage footprint, equipment flexibility and cost for fixed and mobile operations. Typical antennas from 60 cm to 1.2 m keep installation practical on vessels, vehicles and remote sites.

Ka-Band

High-throughput broadband

Built on High Throughput Satellite (HTS) platforms, Ka-Band delivers enterprise-grade bandwidth at the most attractive cost-per-megabit, made for data-intensive, digital-first operations that live in the cloud.

C-Band

Maximum availability

Operating at lower frequencies, C-Band delivers the highest resistance to rain fade and severe weather, the choice where an interrupted link means operational, safety or financial consequences.

Service models

Pay for certainty, scale for flexibility

Every operation weighs guaranteed performance against cost efficiency differently. Our two core models — and fully managed end-to-end options — cover the full spectrum.

Dedicated bandwidth

Satellite capacity allocated exclusively to your operation. No congestion, no contention, no traffic fluctuations from other subscribers, just predictable throughput and a consistent application experience, backed by defined service levels.

Best for: mission-critical applications where guaranteed performance is non-negotiable.

Shared services

A committed Minimum Information Rate (MIR) that is always yours, with burst access to shared network capacity whenever resources are available. Guaranteed reliability for critical applications — without paying for peak capacity around the clock.

Best for: operations that need assured connectivity with cost-efficient, scalable headroom.

Frequently Asked Questions

What is VSAT?

VSAT stands for Very Small Aperture Terminal, a satellite ground station with a compact antenna (typically 0.6–2.4 m) that connects remote sites, vessels and mobile assets to the internet and private networks via geostationary satellites. VSAT provides reliable broadband where terrestrial networks are unavailable or insufficient.

What is maritime VSAT?

Maritime VSAT is a stabilized VSAT system engineered for vessels. The antenna continuously tracks the satellite while the ship moves, pitches, and rolls, delivering always-on broadband for operations, safety, and crew welfare across oceans , including areas with no coastal network coverage.

How does VSAT work?

The onboard terminal transmits to a geostationary satellite 35,786 km above the equator; the satellite relays traffic to a ground station, which routes it to the internet or a private network. The return path is identical, giving vessels continuous two-way connectivity.

How much does VSAT cost?

Pricing depends on the band, coverage area, committed bandwidth and service model (dedicated vs shared). Shared services with a committed Minimum Information Rate offer the most cost-efficient entry point; dedicated bandwidth carries a premium for exclusive capacity. Contact us for a tailored quote based on your requirements.

Is Starlink a VSAT?

Technically, Starlink terminals are a form of very small aperture terminal, but in the maritime industry "VSAT" conventionally refers to stabilized GEO satellite systems. Starlink is a LEO service with different coverage, latency, and service-level characteristics. Many operators run both: GEO VSAT for guaranteed global coverage, LEO for high-speed capacity where available.

What internet speed can I get with VSAT at sea?

Depending on antenna size, frequency band, and plan, maritime VSAT delivers from a few hundred Kbps up to several tens of Mbps. With optimization software such as OptiConnect, even low-bandwidth links support videoconferencing and telemedicine.

Is VSAT reliable in bad weather?

Yes , particularly on Ku- and C-band frequencies, which resist rain fade well. For maximum uptime, IEC Telecom recommends dual-band terminals or hybrid setups with automatic L-band fallback during severe weather.

Can VSAT work together with Starlink or 4G?

Yes. Modern hybrid solutions combine VSAT, LEO, and GSM connections in one centralised network management system such as optiview Optiview to automatically routing traffic over the best available network for performance and cost.

Do you provide support after installation?

Yes, every deployment is backed by proactive network monitoring, service management via OptiView, and 24/7 technical support from our global support centres.
