Section II: Object of the contract
The Air Defence and Air Traffic Services Delivery Team (ADATS-DT) have a requirement for the provision of a Remediation Solution from Industry to eliminate the susceptibility of the radar to interference as a result of the introduction of these New Communications Signals. There are approx. 37 Watchman radars owned by the MoD in a number of different configurations worldwide and the Contractor will be required to supply the interference solution as a modification.
It is assumed that implementation of the ‘Auction for spectrum 2010 to 2025 MHz and 2500 to 2690 MHz’ document is to be used for the definition of 2500 to 2690 MHz signals in the design and build of the remediation solution, and in this document, the maximum number of paired and unpaired lots is used and base stations occupy the highest frequencies in the 2500 to 2690 MHz band plan as set out below.
There is an assumption for the project that there will be a division of the relevant section of the spectrum into multiple channels or bands and that this will be required to facilitate the analysis for the Remediation Solution design needs.
The summary of the assumptions for the 2500 to 2690 MHz band layout is:
— 14 paired lots for uplink at 2500 to 2570 MHz paired with lots for downlink at 2620 to 2690 MHz.
— 9 unpaired lots at 2570 to 2615 MHz for both uplink and downlink.
— 1 guard block at 2615 to 2620 MHz.
— 1 restricted block as the lowest block for each unpaired assignment.
— Maximum transmit power limit:
— Downlink (base, central or broadcasting station).
— Unrestricted channel: 61dBm/5 MHz EIRP o Restricted channel: 25dBm/5 MHz EIRP o Optional power limit for antenna height less than 5m above ground level or indoor antenna: 25dBm/5 MHz EIRP, Uplink (terminal or user station)
— Fixed/installed station: 35dBm/5 MHz EIRP.
— Mobile/nomadic station: 31dBm/5 MHz Total Radiated Power.
— The layout also assumes Frequency Division Duplex (FDD) for paired lots and Time Division Duplex (TDD) for unpaired lots and the following worst case scenario (WCSc).
— Number of 5 MHz Base Station channels transmitting at maximum power in one location = 14 FDD and 9 TDD o Number of FDD service providers at one BS location = 4 o EIRP per 5 MHz channel (dBm) = 61.
— Nominal range of BS mast (km) = 1.
— Nominal height of BS antenna (m) = 25 o EIRP PSD assumptions = As per EU decision
The summary of the assumptions for the 3400 to 3800 MHz band layout will be provided at a later date.
The use of the phrase ‘one location’ refers to a physical area where the presence of multiple communications sources can be regarded as co-located for the purpose of the Remedial Solution Radar Performance Criteria and CAP 670 Radar Requirements.
— Power is the mean power.
— EIRP is Effective Isotropic Radiated Power.
— PSD is Power Spectral Density (dBm/MHz).
— FDD means Frequency Division Duplex.
— TDD means Time Division Duplex.
The radar parameters of the Solution design shall be provided and verified by the Contractor and agreed with the MOD.
The Contractor will need to have regard to all relevant standards for the New Communications Signals.
REMEDIAL SOLUTION RADAR PERFORMANCE CRITERIA.
— In the absence of the New Communications Signals there shall be no measurable degradation in radar performance at any permitted radar operational frequency.
— In the presence of the New Communications Signals there shall be no measurable degradation in radar performance at any permitted radar operational frequency.
— All radar parameters that are required to maintain radar performance shall not be degraded by the Remedial Solution.
Because the final radar bandwidth is the bandwidth used to determine radar performance, it is assumed that for the analysis of radar performance and design issues associated with signal level saturation / non linearity effects, there is no communication signal leakage directly into the final radar bandwidth.
The Remedial Solution shall not be deemed to have failed to meet the Remedial Solution Radar Performance Criteria as a result of communications signal leakage appearing directly into the final radar bandwidth as this is regarded as outside the scope of any radar solution.
ACCEPTANCE TESTING – REMEDIATED RADAR.
The following acceptance criteria shall apply: The Contractor shall provide evidence that the remediated radar meets the Remedial Solution Radar Performance Criteria both with and without any communications signal input, using:
— measurements and analysis during the contract programme to establish component and sub-system compliance with requirements.
— measurements and analysis of the performance of the Existing Radar and the Prototype Modified Radar against the Remedial Solution Performance Criteria.
— full details of the Acceptance Tests which evidence that the performance of the Modified Radar meets the Remedial Solution Performance Criteria.
— and provide evidence of performance against the CAP670 Radar Requirements.
The acceptance testing signals representing the WCSc shall be generated by the use of a standard communications signal generator providing LTE and WiMAX signals.
The Remedial Solution Radar Performance Criteria shall be assessed for the permitted operational frequencies of the ATC radar f1 to fn.
The Contractor shall supply fully documented engineering analysis to establish that the above requirements have been complied with and, in particular, that the input signal levels and WCSc as stated have been correctly evaluated and the resultant performance of the radar meets all relevant criteria.
Interested companies are to note that the Watchman system was purchased as a COTS product and that they will need to satisfy themselves and certify to the Authority, that they can obtain access to any necessary IPR in order to provide a solution to the Interference problem. Or alternatively that no such access is required. Interested companies should consider that they may need to enter into a licence agreement with Selex Integrated Systems Ltd who are the MoD Design Organisation and the owners of IPR in MoD owned Watchman radar.
Description of these options: The Authority may require the contractor to embody the modification in MoD Watchman radars.
Section III: Legal, economic, financial and technical information
A full list of the Regulation 23(1) and 23(2) criteria are at http://www.contracts.mod.uk/delta/project/reasonsForExclusion.html#dspr.
Candidates will be required to sign a declaration confirming whether they do or do not have any of the listed criteria as part of the pre-qualification process. For candidates who are registered overseas, you will need to declare if you have any offences/misconduct under your own countries laws, where these laws are equivalent to the Regulation 23 lists.
Candidates who have been convicted of any of the offences under Article 45(1) are ineligible and will not be selected to bid, unless there are overriding requirements in the general interest for doing so.
Candidates who are guilty of any of the offences, circumstances or misconduct under Article 45(2) may be excluded from being selected to bid at the discretion of the Authority.
Section IV: Procedure
Additional information about electronic auction: Yes. A Reverse Auction, conducted using electronic means, may be used as part of the procurement process for this requirement. Specific relevant information on Reverse Auction usage will be given in the Invitation to Tender.
Section VI: Complementary information
Suppliers interested in working with the Ministry of Defence should register on the MOD Supplier Information Database (SID) Register, available at www.contracts.mod.uk. The MOD SID is a database of active and potential suppliers available to all MOD and UK Defence procurement personnel, and is the main supplier database of MOD Procurement organisations. Please note: the registration and publication of a company profile on the MOD SID does not mean or imply that the supplier has in any way been vetted or approved by the MOD. Suppliers wishing to compete for advertised MOD contracts must respond to any specific call for competition by submitting a separate expression of interest in accordance with the instructions of the purchasing organisation.
