  to the branch plans foreseen in the current operation and prepares orders necessary to implement a sequel to
  the operation.
  4-42. A running estimate is the continuous assessment of the current situation used to determine if the
  current operation is proceeding according to the commander’s intent and if planned future operations are
  supportable (ADP 5-0). Failure to maintain accurate running estimates may lead to errors or omissions by
  future operations which may result in flawed plans and bad decisions during execution. Running estimates
  always include recommendations for current and anticipated decisions affecting friendly and enemy forces.
  It is the responsibility of the space operations officer to maintain a space running estimate.
  4-43. The space running estimate provides the means to conduct space effects tracking and assessment
  throughout the battle. The space running estimate provides plans and tactics for the protection of space
  capabilities and enemy countermeasures. This includes new facts and assumptions, as the situation changes
  and the operation proceeds. New facts and assumptions generate conclusions, and recommendations for the
  commander in terms of how space capabilities influence and impact the mission.
  4-44. Space operations officers develop and maintain the space running estimate. For echelons below
  division, units may rely on the higher command’s space operations officers to provide the space running
  estimate. The space running estimate describes how space influences and impacts mission at echelons of
  brigade and below. The space running estimate is not a standalone staff estimate, but rather a series of
  estimates, which support, and is integrated into the staff estimates of other staff elements.
  4-45. The information maintained within the space running estimate supports the unit’s ability to perform
  command and control, information collection, target development, targeting, movement and maneuver, and
  battle damage assessment. Examples of information tracked within the space running estimate includes but
  is not be limited to:
  * Type, quantity, status, intentions, tactics, and known or suspected locations of threat GPS and
  SATCOM jammers (active and inactive). This information supports the G-2’s ability to develop
  and maintain, the enemy electronic order of battle which sets the conditions for the development,
  refinement, and assessment of the information collection plan and the development of lethal and
  non-lethal targeting options for the commander.
  * Ongoing or anticipated areas impacted by GPS jammers and the corresponding effects on GPS-
  enabled equipment such as:
  FFT devices, radios, and unmanned aircraft systems;
  o
  GPS-aided precision guided munitions;
  o
  GPS-aided target acquisition systems;
  o
  * Ongoing or anticipated areas impacted by SATCOM jammers and the corresponding effects on
  SATCOM and SATCOM-enabled equipment such as:
  Warfighter information network–tactical;
  o
  Joint Battle Command-Platform;
  o
  Command post of the future;
  o
  Force XXI battle command, brigade and below; and
  o
  U.S. Marine Corps joint capabilities release.
  o
  * Ongoing or predicted impacts of terrestrial and space weather effects on GPS; SATCOM; space-
  based surveillance and reconnaissance; and missile warning systems, platforms, and architectures.
  * Satellite reconnaissance advanced notice reports provide predicted overflights of enemy satellites
  by type/sensor and associated surveillance and reconnaissance tasking over friendly area of
  operations to the staff.
  * Predicted periods when GPS is degraded and the impacts on GPS guidance accuracies and
  employment times/locations of GPS aided munitions. This information is assessed using
  positional dilution of precision values in charts and graphs, and directly supports fires by assessing
  the proper employment of precision guided munitions at specific times and locations.
  * Assessments of the adversary’s reliance on organic, commercial, or third-party space capabilities
  such as SATCOM; space surveillance and reconnaissance; GNSS; and environmental monitoring.
