MULTI LINK ROUTING SIMULATION: Using the Patented STARMESH    Satellite Constellation 

TM

1. MAP OF AFRICA

Lagos is one of the largest and most civilized cities in sub-Sahara Africa.  Lagos has an excellent cable Internet connecting it to the rest of the worldwide Internet. The goal of this simulation is to demonstrate that Lagos can utilize its main Internet hub to spread Internet to various other cities in all of Africa. We have elected to select cities that are well known in Africa, as that will help the user follow the simulation.

3. AFRICA WITH STARMESH    ROUTE CREATION

TM

We now send messages of real data to Lagos that arrive via cable and ask Lagos to select a satellite to forward the message to another city in Africa. Messages arrive at the rate of about 10 per second and are directed to randomly chosen destination cities in Africa. Each StarMesh™ satellite has multiple antennas that have focused beam widths that cover about 30% of the spherical space (the rest is solar panels). Thus, for a probabilistic connection one antenna is pointing at Lagos and the second one pointing at the destination city. The antennas are of limited focus so as the simulation progresses, some messages end up in a queue at the Lagos ground station.  The columns on the edge show message arrivals and deliveries.

2. AFRICA WITH STARMESH     SATELLITES IN ORBIT

TM

The StarMesh Global™ patented technologies enable a low-cost solution to spread the Internet using proprietary satellites in unconstrained (random) orbits without attitude control. This real-time simulation demonstrates the number of random global orbiting StarMesh™ satellites that would be over the African region at any given time in a StarMesh constellation of 220 total satellites. These satellites are at an altitude of about 500 miles and are moving at about 18,000 miles per hour. An interesting observation is that in spite of the fact of their high speed these satellites change relative positions more slowly than expected.

4. STARMESH    Multi-Link SATELLITE Routes W/ STATS

TM

Some routes in the simulation are by the bent pipe approach (one link up and one link down) and some include inter-links (satellite to satellite). After a 20 second interval the satellites change relative positions, so we are faced with a new set of probabilities for each satellite and its relationship to both Lagos and the destination cities. This StarMesh Global™multiilink routing simulation utilizes ground to satellite and satellite to satelite links in routes to improve the operation and reach of the previous Phase I simulation of primarily bent pipe routes. It also greatly expands connected service to distant locations as well as refines service to close by locations.
