Certus 100 has faster data speeds
RUDICS transmits data at 2.4 Kbps; Certus 100 transmits data at 22 Kbps, and the downlink is 88 Kbps – almost 40 times faster. This means that you can transmit more data, more frequently.
Costs / billing mechanism
RUDICS is charged per minute, rather than the Certus 100 charging model of per byte of data transmitted. This makes RUDICS more expensive than Certus 100 for many applications; it’s possible, even probable, that you’re paying for connectivity time you don’t need.
RUDICS is circuit-switched
RUDICS is circuit-switched, which means the ‘call’ between the remote device and the server has to be maintained. It’s not fault tolerant if your view of the satellite is temporarily obscured, or the server goes offline.
Certus 100 is packet-switched
Certus 100 is a packet-switched network, sending data in small and optimised packets which are much less likely to be ‘dropped’ mid-transmission.
