  Objective:  Develop an omni-directional capability for transmitting tactical imagery and data to improve the SHARP data link field of view
  Description:  New technologies, including transmission control protocol/internet protocol (TCP/IP) can improve omni-directional transmissions in a tactical environment. Omni-directional capability will increase the amount of operational time that SHARP data can be transferred to ship/shore/ground active sites. Currently, the data link beam is directional, and the data link is not operational during some aircraft maneuvers and flight profiles. Adding an omni-directional capability will enable data exchange to continue even during most aircraft maneuvers and will improve data transmission time to the greatest number of weapons platforms, both airborne and on the ground. It will also provide a capability for near real time sensor to shooter data transfer in a tactical (hot) environment by improving the data link’s field of view and transmission range compared to an existing directional data link.

  PHASE I: Determine the feasibility of improving the omni-directional transmission of tactical imagery data and the SHARP data link field of view.
  PHASE II: Develop a prototype of the omni-directional antenna and incorporate the proposed transmission technology into the SHARP data link system. Demonstrate improvements in the data link’s transmission range and field of view.

  PHASE III: Integrate the omni-directional antenna and associated transmission technology into the SHARP pod. Perform flight tests to demonstrate improvements in data link connectivity during all aircraft maneuvers and environmental conditions. PRIVATE SECTOR COMMERCIAL POTENTIAL/

  DUAL-USE APPLICATIONS: Rapid air to ground wide area coverage is needed for search and rescue in different types of environments from remote areas to urban applications. It can be used in disaster relief to coordinate the rapid response teams to the most critical sites. It can also be used in border protection and security by coordinating wide area ground surveillance and with mobile border patrol teams. The same application can be used by DEA for drug traffic interdictions.

Questions and Answers:
Q: What is the full frequency range of operation desired?
A: . . . response pending . . .
Q: 1. What is the desired frequency band for the expanded data link (the same as the existing Ku link)?

2. Are there candidate locations on the pod for the new antenna(s)?

3. The present directive data link has a limited scan (+/- 90 deg Az & + 10 to - 60 deg in El), so what is your goal for the improved field of view?
A: 1. 14.40 to 14.83 GHz for the Return Link, 15.15 to 15.35 GHz for the Forward (command) Link

2. No.

3. 360 degrees.
Q: 1. What is the data rate to be via this Omni antenna?
2. Are you truly wanting Omni coverage or is something less than Omni acceptable (ie...cone of silence directly under the antenna??)
A: 1. Up to 45Mbps

2. A cone of silence directly under the antenna is acceptable.
Q: What is the minimum signal level at the video receiver for acceptable performance?
A: This varies by ground receiver station but our goal is to provide the best imagery transmission with minimal data loss even if it means sacrificing range.
Q: 1. What is the desired polarization of the omni antenna?

2. Is the design of a radome for the antenna part of the requirement?
A: 1. Circular

2. Yes.
