Using the “Save As” function of the TDV application, we then exported each of the datasets to a delimited text file format. An excerpt from one of these datasets is shown in Table 6-28: Table 6-28. An example of data exported from TDV to a delimited text file format. Date Track ID Update Time Intensity Range (m) Azimuth (deg.) Height (m) Heading (deg.N) Speed (m/s) Latitude Longitude UTM Zone UTM Northing UTM Easting 9/12/2009 888 00:00:03.6 1300 837.09 308.7 58.4 177.3 11.3 47.4464 -122.3092 10T 5255005 552081 9/12/2009 888 00:00:06.0 1445 821.59 307.4 57.3 177.4 11 47.4462 -122.3092 10T 5254981 552083 … … … … … … … … … … … … … … Finally, we imported the two delimited text files into separate worksheets in a Microsoft Excel® workbook, which we used to compare the Update Times of the two datasets in a cell-wise manner according to the following formula: =IF(RDS!C1=DRP!C1,0,1) Where RDS! refers to the dataset from the RDS and DRP! refers to the dataset extracted from the DRP. We wrote this formula to output a ‘0’ if a match was found between corresponding cells or a ‘1’ if corresponding cells were not identical. Figure 6-97 is an example of this comparison: Figure 6-97. Comparison of the Update Times from the RDS dataset (left pane) with those from the DRP dataset (middle pane). The right pane indicates if the two Update Time values were the same (‘0’) or different (‘1’). We then summed the number of records where the Update Time values were different (‘1’) and used this value to calculate the wired WAN network availability. Results There were 41,196 records (“updates”) in the 12 September 2009 dataset transferred from the SEAAR1l DRP. Thus, our success criterion of 50% network availability was equivalent to fewer than 20,598 Update Time values that were different between the DRP and RDS datasets. Table 6-29 summarizes the actual number of different Update Time values. 222
Table 6-29. Differences found between the Update Time values of the local DRP dataset and those of the remote RDS dataset from the AR2-1 avian radar at Seattle-Tacoma International Airport on 12 September 2009. Dataset (2009.09.12) Number of Updates Differences Found Availability (%) RDS at ARTI 41,196 SEAAR1l DRP at SEA 41,196 0 100 The Updates Times from the two datasets of 41,196 records each were identical, indicating 100% (calculated) network availability. Conclusion Using the methods described above, we successfully demonstrated 100% network availability for a wired WAN (the Internet) over a 24-hour period, a level of availability much higher than the success criterion of 50%. A wired WAN (the internet) provides the avenue by which all remote units (DRP, RDS, TVW, etc.) of the system are connected. Reliability of this network is essential for real-time monitoring of avian hazards and transferring data through the RDS. 6.3.1.7 Wireless LAN Availability [SC4.1] Objective We designed Performance Criterion SC4.1 to assess the wireless connection uptime at two remote IVAR study locations that continuously stream target data back to an RDS at ARTI. We proposed to do this through a pair-wise comparison of the scan times as generated over a 24-hour period by the DRP and those extracted for the same time period from the RDS. We proposed to measure the LAN availability as the number of scans generated by the DRP that were missing from the RDS. The two locations we proposed to use for this demonstration and the corresponding wireless network connections were: NASWI, which has Internet access through both a cellular network air-card and a Wireless Fidelity (WiFi) IEEE 802.11b access point with a directional antenna; and SEA, which has a point-to-point WiFi link to an internal network. Users of avian radar systems expect the availability of a wireless network to be reasonably high, as they require real-time access to the radar data from remote locations, especially those on the airfield. We therefore established the metric for the successful demonstration of Performance Criterion SC4.1 that the calculated availability of each of the wireless LAN connections must be at least 50%. Methods We selected two radars to demonstrate SC4.1: The midfield radar at SEA, SEAAR1m, because it is the only wirelessly connected radar installation at that location; and the eBirdRad at NASWI, because of its long period of continuous operation. We chose 12 May 2009 and 26 November 2009 as the 24-hour continuous datasets for the SEAAR1 and eBirdRad radars, respectively. During the periods of continuous operation, the DRPs of each radar archived plots and tracks data locally. They also streamed those same data continuously to a remote RDS at ARTI. We assumed the locally archived plots and tracks datasets to be lossless (containing every scan of 223
