View source for VITA 49

The VITA Radio Transport standards encapsulate RF data. It emphasizes precise timestamps and rich signal information, and seeks to be a common means of moving custom analog IC logic into COTS digital networks--a kind of virtual [[SDR]]. The [https://www.vita.com/Standards published standards] are not offered freely, save to VITA associates.

==Receipt==
* Context packet -- describes properties of the radio components and antenna
** DDC: tuning, bandwidth
** ADC: sample rate, triggering
** RF tuner: bandwidth, gain, phase lock
** Antenna: azimuth, angle, polarization, location, altitude, speed, heading
* Signal packet -- IF/digitized RF/baseband data, ID, timestamp, spectral survey
** supplied by the DDC
* VRT information stream combines Context and Signal packets
* Configuration remained ad hoc in VITA 49, added in VITA 49.2 as Control Packets
** Uses same fields as Context packets
** ACKed by controlled devices
** Can be used to interrogate device properties on demand
** Can program simple loops and event triggers
** Very similar to [[CAN bus|CAN]] in these regards

===Context descriptors===
* 1-D Pointing Angle, ADC Sample Rate, Bandwidth, Frequency, GPS Coordinates, Velocity Vector, Power or Gain Settings, Reference Point, Timestamp, System Latency, 2-D Pointing Angle, Antenna Beamwidth, Noise Figure, Phase, Polarization, Relative Time Stamp, Scan Control, SNR, Waveform Type

==Transmission==
* Signal packets containing waveform and time schedule
*
