A method for determining heave and heave rate for a vessel is described. A muting state is detected at a particular endpoint during the conference session and the multimedia from the particular endpoint is recorded even though it is not forwarded and rendered to the other endpoints during the conference session. The adjusted orbit model comprises the long-term-satellite-tracking data. Combining this plurality of values enables appropriately compact data from the sensor chip. Consequently the encasement medium functions as an effective stress translating medium that deliberately translates stresses on the cable to the optical fibers.
