Inter Satellite Link Budget

The satellite link will use tdm to bundle all the packets and send them in one large 100 mbps data link.

Inter satellite link budget.

The inter satellite link transceiver to be able to establish the space wireless network. In general these calculations are called as link budget calculations the unit of power is decibel. Radio link design the goal of radio link design is to ensure that a reliable. The link budget for the inter satellite link between an existing satellite mission such as spot 6 and a conceptual satellite negotiator was estimated.

Atmospheric losses at 437 mhz minimum maximum minimum maximum elevation l atm db l atm db l sci db l. As i can see one of the main distinction of optical link is that we need to configure the direction as opposed to radio where we emit the signal broadly. The budget result of the information transmission rate of the 810 nm wave length laser link is indicated as fig. First let us discuss the basic terminology used in link budget and then we will move onto explain link budget calculations.

Uplink antenna diameter m. Small satellite link budget calculation. Analysis of the laser link budget results. Complete all boxes in the white rows and then click any calculate button to obtain results in the green rows.

Prompted by the limited number of link budget studies for cubesat radio systems this paper aims at augmenting exist. Uplink antenna aperture efficiency e g. This should be enough bandwidth to handle all realistic communication scenarios. Satellite link budget calculator.

In satellite communication systems there are two types of power calculations. First inter satellite radio link was established in 1975 first inter satellite laser link in 2001. Those are transmitting power and receiving power calculations. 23 46 critical points in a satellite link received power noise signal to noise ratio conclusions friis formula antennas polarization propagation humsat d.

Diameter satillite antenna m. The inter satellite laser link budget takes the commonly used 810 and 1550 nm wave length laser as example with the inter satellite distance as 41263 405 km zhao et al 2011.
