  4 +
  5 +GLORI is based on a dual antenna setup:
  6 +
  7 +- one uplooking aka Zenith Antenna
  8 +- one downlooking aka Nadir Antenna
  9 +
  10 +The zenith antenna is Right Hand Cicular Polarized, the Nadir antenna has dual polarization capabilities
  11 +
  12 +- one output for Left Hand Cicular Polarization (LHCP)
  13 +- one output for Right Hand Cicular Polarization (LHCP)
  14 +
  15 +If active antennas are used, power has to be provided through a bias tee.
  16 +
  17 +
  18 +GLORIE 2015 version
  19 +===================
  20 +
  21 +Zenith Antenna
  22 +--------------
  23 +
  24 +- The zenith Antenna is a :ref:`Antcom_42G1215RL` in the same configuration
  25 + as in the `KuROS 2014 version`_
  26 +
  27 +
  28 +Nadir Antenna
  29 +-------------
  30 +
  31 +- The Nadir antenna was changed for a :ref:`Cobham_DS1563`.
  32 +- It is linked to the :ref:`INS_calib` by 50 cm low loss coaxial cables.
  33 +- Low Noise amplification is now performed by discrete components
  34 + within the :ref:`INS_calib`.
  35 +
  36 +
  37 +KuROS 2014 version
  38 +==================
  39 +
  40 +Zenith Antenna
  41 +--------------
  42 +
  43 +- The zenith Antenna is a :ref:`Antcom_42G1215RL`.
  44 +- It is powered by a bias tee placed directly on the antenna.
  45 +- Low loss 10-meter cables are used.
  46 +- Only the RHCP port is used.
  47 +- A 50 Ohm Load is plugged to the LHCP port.
  48 +
  49 +
  50 +Nadir Antenna
  51 +-------------
  52 +
  53 +- The Nadir Antenna is also a :ref:`Antcom_42G1215RL`.
  54 +- It is powered by a bias tee placed in the Front end.
  55 +- Because of current draw by the filters, one more bias tees is used, on the
  56 + other polarization channel.
  57 +- Low loss 10-meter cables are used.

2 4 Calibration Module
3 5 ******************
  6 +
  7 +Goal
  8 +====
  9 +
  10 +The goal of the calibration module is to be able to perform a relative
  11 +calibration of both reflected polarization and also relative calibration of
  12 +reflected channels vs. direct channel. For this purpose, it includes a set
  13 +of transfer switches allowing to send any input RF signal on any of the
  14 +Front end inputs.
  15 +
  16 +The calibration module was originally part of the front end in the KuROS
  17 +2014 version. With the use of passive antennas, it was moved next to the
  18 +antenna in order to be able to calibrate the whole cable and amplifiers and
  19 +to minimize the losses.
