Of the 491 bursts in that catalog, covering 2008 July 12 to 2010 July 11, 427 were observed by at least one other instrument in the nine-spacecraft IPN. Of the 427, the localizations of 149 could be improved by arrival time analysis (or "triangulation"). For any given burst observed by the GBM and one other distant spacecraft, triangulation gives an annulus of possible arrival directions whose half-width varies between about 0.4' and 32{deg}, depending on the intensity, time history, and arrival direction of the burst, as well as the distance between the spacecraft. We find that the IPN localizations intersect the 1{sigma} GBM error circles in only 52% of the cases, if no systematic uncertainty is assumed for the latter. If a 6{deg} systematic uncertainty is assumed and added in quadrature, the two localization samples agree about 87% of the time, as would be expected. If we then multiply the resulting error radii by a factor of three, the two samples agree in slightly over 98% of the cases, providing a good estimate of the GBM 3{sigma} error radius. The IPN 3{sigma} error boxes have areas between about 1 arcmin^2^ and 110 deg^2^, and are, on the average, a factor of 180 smaller than the corresponding GBM localizations. We identify two bursts in the IPN/GBM sample that did not appear in the GBM catalog. In one case, the GBM triggered on a terrestrial gamma flash, and in the other, its origin was given as "uncertain." We also discuss the sensitivity and calibration of the IPN. Description: This paper presents the latest in a series of catalogs of gamma-ray burst (GRB) localizations obtained by arrival time analysis, or "triangulation" between the spacecraft in the third Interplanetary Network. we present the localization data on 149 bursts which occurred during the period covered by the first, two-year Fermi Gamma-Ray Burst Monitor (GBM) GRB catalog (Paciesas et al. 2012, Cat. J/ApJS/199/18; 2008 July 12 to 2010 July 11). Every cosmic burst detected by the GBM was searched for in the IPN data; GBM localizations were used to calculate arrival time windows for Odyssey and MESSENGER, but the total crossing time windows defined by light-travel times were examined in all cases. The resulting detections are given in Table 2. Konus and Suzaku can detect bursts in both triggered (2-64ms time resolution) and an untriggered (1-3s time resolution) modes; both modes are counted as detections in this table. Also, detections by several instruments which are not part of the IPN have been reported in the table, namely the Fermi LAT, Monitor of All-sky X-ray Image (MAXI), and Rossi X-Ray Timing Explorer (RXTE).
