LinkMeasurement(std::vector<NaifId> occult_bodies, VecXd occult_alt, Real hardware_delay)

Construct a new Isl Measurement object using transmitters and receivers.

Parameters:

• occult_bodies – occulting bodies

• occult_alt – occultation altitude

• hardware_delay – hardware delay

• link_type – link type (e.g. “one-way”, “two-way”, “dual-one-way”)
