Satellite Network latency chart for a WAN Emulator

Hi Guys,

I am working on an open-source WAN Emulator called TOFFEE-Mocha. Along with other WAN Emulation features you can configure packet latency in milliseconds and microseconds in the same.

But to emulate satellite networks I need a chart consisting Satellite Network technologies (standards/specs) and the corresponding latency in some form of chart.

If case if you guys have the satellite networks latency chart can you please forward me the same?

Besides if you are looking for any new features specific to satellite networks can you suggest me the same. Here is my project URL: https://www.the-toffee-project.org/

Hi,

Please dont forget other factors contributing to the latency, such as buffer size and FEC block size (which varies as well according to the data rate). Also spoofing and other packet related processing should contribute to the latency.

A novel medium height satellite network has become operational in the last few years, called O3b.

O3b is an operating constellation of 12 satellites, spaced at 40 deg intervals along a single medium height orbit directly above the equator. The height is 8062km and this results in lower latency compared with geostationary. This is a key selling point. If a typical single hop path involves two sloping path lengths of 11000km the single hop distance is 22000km with a latency of 73 mS. O3b claim a "round trip" latency of better then 150mS. Their 150 mS "round trip" definition refers to a double hop distance of 11250 + 11250 + 11250 + 11250 km.

Speculative future low earth orbit (LEO) satellite networks with constellations of hundreds of satellite may operate with lower orbit heights like 1200 km.

The speed of radio waves is 300,000 km per second.
