technology in radio astronomy and geodesy. In partnership with Thoth Technology Inc., our team of leading radio astronomers will (i) develop new capabilities to compress, transport, and process large amounts of data between geographically distinct locations to enable real-time VLBI, and (ii) use this capability to make precise astrometric measurements of Fast Radio Bursts (FRBs) and pulsars, and through their scintillation properties, study their local environments. The program will have several far-reaching benefits. Scientifically, advances to VLBI will improve the precision of pulsar localization by orders of magnitude and allow for a systematic spatial localization of FRBs. The project will also position Canada's Algonquin Radio Observatory as the nexus of a new, low-frequency, global VLBI network and Thoth Technology as one of the world's premier VLBI providers to large-scale, international telescopes. More far-reaching still, next-generation VLBI will underpin the high-precision geodetic reference frame upon which autonomous vehicles will rely. As such, advances to VLBI could profoundly impact nearly every aspect of our economy, from engineering and construction to transportation and precision agriculture.

射电天文学和大地测量学技术。与Thoth Technology Inc.合作，我们领先的射电天文学家团队将（i）开发新的能力，以压缩、传输和处理地理上不同位置之间的大量数据，从而实现实时VLBI;（ii）利用这种能力对快速射电暴（FRB）和射电星进行精确的天体测量，并通过它们的闪烁特性研究它们的局部环境。 该计划将有几个深远的好处。VLBI技术的进步将使脉冲星定位的精度提高几个数量级，并允许对FRB进行系统的空间定位。该项目还将把加拿大的阿尔冈琴射电天文台定位为一个新的低频全球VLBI网络的连接点，并将Thoth Technology定位为世界上大型国际望远镜的主要VLBI供应商之一。更深远的是，下一代VLBI将支撑自动驾驶汽车所依赖的高精度大地测量参考系。因此，VLBI的进步可能会深刻影响我们经济的几乎每个方面，从工程和建筑到交通运输， 精准农业
