ACS has expertise in conducting thorough site surveys based on years of experience and hundreds of completed site surveys.  This includes ground based NAVAIDS such as VOR, DME, TACAN, ILS, NDB, DGPS/DGNSS, and Approach Lighting.  ACS also surveys communications systems such as VHF/UHF, microwave, HF, VCCS, and remote control and fiber optic networks.  Radar expertise includes primary, secondary, precision approach, and surface surveillance systems. 

Our approach to site surveys includes a complete evaluation of the site, how existing equipment is performing and how they comply with the applicable siting requirements, future implications of facility expansion or planned buildings, affect of one system on the others, and finally modeling of the proposed system to confirm the on-site findings.

ACS also carries out area surveys and Equipment precision location services using WGS-84 certified personnel and state-of-the-art equipment.  This service can be offered at the time of the preliminary site survey, or at the initial stages of installation of equipment.

A comprehensive report with all needed backup information and references is then generated with an executive summary of the findings.  The report also contains recommendations as well as a detailed technical assessment of the site.

All of our site survey reports come with comprehensive validated computer modeling to ensure the accuracy of the equipment placement and the required system performance.

Our Engineers have the theoretical and practical product background in surveillance, ground based NAVAIDS, and Communication that allows us to use highly advanced performance modeling software to predict the performance of equipment prior to installation.

Typical outputs from this modeling will include options for siting of the equipment, proposed configurations, and any required modifications or enhancement to the proposed site.

ACS has on-going contracts to offer our services to manufacturers during the bidding or installation phase and to end customers during the tender preparation or requirements analysis phase.

Conclusions from the modeling are typically presented in graphical as well as narrative format to explain the results.

We have experience with a majority of the available equipment on the market and can best serve our customers by reducing costs typically incurred during installation related to equipment not being compatible with the proposed sites.

Our highly trained engineering workforce is routinely involved in every phase of program development. Participation begins in design, then continues through test and integration to after-market support. This depth of involvement ensures an unsurpassed level of customer support.
