Frank van Diggelen

Van Diggelen was born in Cape Town{{Cite web |last=Rino |first=Charles |date=23 August 2018 |title=Oral History of Frank van Diggelen |url=https://archive.computerhistory.org/resources/access/text/2018/11/102738864-05-01-acc.pdf |website=Computer History Museum}} to Tromp and Judith van Diggelen during the apartheid era. As a child, he became interested in engineering through making Meccano sets with his mother.{{Cite web |last=GNSS |first=Inside |date=2015-01-16 |title=Frank van Diggelen: Riding the GNSS Wave |url=https://insidegnss.com/frank-van-diggelen-riding-the-gnss-wave/ |access-date=2023-01-28 |website=Inside GNSS - Global Navigation Satellite Systems Engineering, Policy, and Design |language=en-US}} He was conscripted to join the South African Navy at 18, working as a navigation officer. He later received a scholarship to attain a Bachelor's degree at the University of the Witwatersrand.{{Cite web |title=GPS.gov: Frank van Diggelen |url=https://www.gps.gov/governance/advisory/members/van-diggelen/ |access-date=2023-01-28 |website=www.gps.gov}} After another successful scholarship, van Diggelen received a PhD in electrical engineering from the University of Cambridge in 1992, advised by Keith Glover. His dissertation was Hadamard Weighting in Robust Control.

Van Diggelen is a Distinguished Engineer at Google, where he heads the GNSS team for Android.{{Cite web |title=Frank van Diggelen |url=http://seminarseries.ucsd.edu/team/frank-van-diggelen-2/ |access-date=2023-01-28 |website=Seminar Series at Qualcomm Institute |language=en-US}} He invented coarse-time GNSS navigation and is the co-inventor of Long Term Orbits (LTO) for A-GPS. Van Diggelen is currently the president of the Institute of Navigation (2021-);{{Cite web |date=29 January 2021 |title=MINUTES OF THE OUTGOING COUNCIL MEETING |url=https://www.ion.org/governance/upload/Minutes-Council-1-29-21.pdf}}{{Cite web |title=ION Executive Committee and Council |url=https://www.ion.org/governance/council-members.cfm |website=Institute of Navigation}} he was previously the vice chair of the institute’s Satellite Division. Van Diggelen has previously held positions at the Navsys Corporation, Ashtech, Magellan Navigation and Global Locate. He has around 100 US patents to his name.

During his time at Cambridge University, Keith Glover (van Diggelen's PhD advisor) recommended van Diggelen for a job with Alison Brown of Navsys, a government GPS contractor based in Colorado Springs. He started working with the company in 1992. During his time at Navsys, van Diggelen assisted with the creation of receiver autonomous integrity monitoring (RAIM) to be used by the U.S. Coast Guard.

After working at Ashtech (which later merged with Magellan Navigation), van Diggelen started work at Global Locate, a California based GPS company. He served as Vice President of technology & chief navigation officer. At Global Locate, he worked on the team that produced the first GPS smartphone chip, used in the HP iPaq. TomTom was also involved in the project and later collaborated with Global Locate to produce the TomTom One. The device used Global Locate's Hammerhead chip, which was also used in the iPhone 3G.

After Global Locate was bought by the Broadcom Corporation, van Diggelen served as the company's Vice President of GPS Technology. At Broadcom, van Diggelen worked on the BCM4771 and BCM4774 GPS chips.

Van Diggelen has also taught extensively. His first teaching experience came during his time at the University of Witwatersrand when he taught mathematics to high school children from Soweto and Alexandra. He is a consulting professor at Stanford University. In 2014, together with Per Enge, van Diggelen conducted a six-week long course on GPS through Stanford University and Coursera.{{Cite web |title=GPS MOOC (Massive Open Online Course) {{!}} Center for Position, Navigation and Time |url=https://scpnt.stanford.edu/about/gps-mooc-massive-open-online-course |access-date=2023-01-28 |website=scpnt.stanford.edu |language=en}}{{Cite web |date=2014-10-14 |title=Massively Online GPS Course Massively Popular |url=https://www.gpsworld.com/massively-online-gps-course-massively-popular/ |access-date=2023-01-28 |website=GPS World |language=en-US}} The course was free and available online as a Massive Open Online Course (MOOC). The course is now available on YouTube. He also taught in Rwanda through the Institute of Navigation Satellite Division’s African Outreach Program. Van Diggelen is the author of the first A-GPS textbook: A-GPS: Assisted GPS, GNSS, and SBAS.

Van Diggelen is married to Alison van Diggelen, a technology journalist.{{Cite web |title=Alison van Diggelen {{!}} HuffPost |url=https://www.huffpost.com/author/alison-van-diggelen |access-date=2023-01-28 |website=www.huffpost.com |language=en}} They met while at Cambridge University. Now living in the San Francisco Bay Area, the couple has two children. In his free time, van Diggelen is fond of sailing, skiing and hiking.
