Iridium has a constellation of 66 satellites, constantly circling the globe in low earth orbit. This means you have reliable connectivity anywhere on earth where you can see the sky. Iridium Certus 100 bridges the gap between narrowband and broadband, with an IP connection enabling higher throughput speeds of 22 Kbps up, 88 Kbps down.
Certus-enabled devices such as the RockREMOTE and RockREMOTE Rugged have small, low profile antennas that are easy to install, robust and discreet; with usage optimization, the devices need little power, and can operate on batteries or even solar power. The antennas are omni-directional, needing no pointing, which makes them highly effective on the move, in mountains, and in wooded areas.

Certus 100 Plans and Pricing
Certus IoT service plans are intended for exclusive use in machine-to-machine, tracking, telemetry, condition monitoring and SCADA applications.
In addition to offering competitive rates and highly flexible plans, Ground Control has a modern, API-first platform (Cloudloop) from which you can manage all of your devices.
With the ability to pool data plans, and set alerts (and even automatic deactivation) if a device is using more data than anticipated, you’ll save money and make your life easier at the same time.
- Pricing in US Dollars, excluding tax
- Monthly Recurring Charge (MRC) is billed monthly in arrears unless otherwise specified
- Overage charges are billed monthly in arrears at the rate specified in the service plan
- Each subscription has a minimum commitment term of 12 months unless otherwise specified
- Early termination fees will be automatically charged for any subscription terminated within the minimum commitment term
- Plan pricing is subject to change with 30 days written notice

*Dynamic Shared Groups (DSG)
Subscribers on eligible service plans within an organization may aggregate their monthly data allowance into a pool which can be shared across all subscriptions.
- DSG is available only on service plans marked as eligible
- All subscriptions in the group must be subscribed to the same service plan
- DSG is charged monthly at additional 10% of the service plan MRC per subscription
- Each billing cycle any data usage that exceeds the DSG pool allowance (overage) will be billed at the overage rate for the subscription plan plus 10%
- Each DSG requires a minimum of five active subscriptions
- Each DSG has a minimum commitment term of 12 months
- Early termination fees will be automatically charged for any DSG terminated within the minimum commitment term
Iridium Messaging Transport Pricing
Iridium Messaging Transport (IMT) uses the Certus 100 service; the plans are the same price and have the same data allowance regardless of whether you’re using IMT, a message-based protocol, or Certus 100, an IP-based protocol. However, the cost of sending your data via IMT is going to be substantially lower than sending your data via Certus 100. This is because there is no TCP/IP overhead in a message-based service; you only send your data payload. The drawback is, IMT is more technically involved to implement.
Basically, if you send your data via Certus 100, as an IP-based service, it’s highly interoperable with your existing software, and integration will be simple. If you send your data via IMT, you’ll need to “chop it up” first, and reassemble it at the far end. If you can do this, it’s a far more cost-effective way of sending data, but needs some programming skill. We’re here to help so get in touch if you’d like some advice on this, or representative costs for using IMT over Certus 100.
