20 InsideGNSS N O V E M B E R / D E C E M B E R 2 0 1 8 member of various U.S. bilateral/ multilateral teams that have met with other GNSS service providers to ensure that other GNSS constel- lations are radiofrequency compat- ible with GPS. "•is has included numerous meetings with Europe, China, Russia, Japan, India, among others," he said, "and has resulted in a number of formal agreements. One challenge we have faced is pro- tecting GNSS from self-interference problems with the rapidly growing number of GNSS satellites, includ- ing SBAS geostationary satellites." • Artech House GNSS Series Co- editor – Since 2006, Hegarty and Elliott Kaplan have been co-editors of Artech's GNSS Series. "Our text, 'Understanding GPS/GNSS: Principles and Applications' is the "agship of the series," Hegarty said. "•e second edition was published in 2006 and the third edition in 2017. Over 7,500 copies of these two editions have sold worldwide thus far. •e second edition has been translated into Chinese, and the third is now in translation. •ere are more than a dozen other titles in the series thus far." Meanwhile, Hegarty has remained busy as a teacher, for a while as a part- time Professor at George Washington University, since 2000 for Navtech Seminars, and also a number of sub- jects internally for MITRE. He has even had occasion to enjoy a few perks: "Every summer but one since 2007, I've taught at what is now referred to as the ESA/JRC GNSS Summer School in Europe," he explained. "•ese have been like vacations for me – a few hours of lecturing, but most of the time spent conversing with the other lecturers and students, or in some scenic location hiking. My son joined me one year in Davos, Switzerland, and we hiked and mountain-biked. Last year, I had the opportunity to spend time in Svalbard, which is about 80N in latitude. •is July the summer school was in Austria and my daughter joined me for her ¢rst trip to Europe." How He Came Full Circle Christopher Hegarty, it can be argued, has it all. But getting it all has implied certain trade-o£s. "One challenge that we've faced is that I've had a lot of work-related travel over the years," Hegarty said. "We've been fortunate that Patti was willing to stop working and stay home to take care of the kids, house, and ¢nances. She has also found time to volunteer at local schools and tutor some high school kids in math- ematics," Hegarty said. •e arrangement seems to have worked. "Michelle and David are now o£ at college – Michelle for graduate studies and David as a college fresh- man. And Megan is 13 and just start- ing eighth grade." "We have and will continue to encourage all of our children to pur- sue their interests in whatever ¢elds that may choose." A wise policy that Hegarty may have picked up from his own parents. For all his accomplishments, fam- ily clearly remains a key source of strength and comfort in Hegarty's life. "Spending time with my wife and kids is extremely important to me, as is get- ting together with extended family," Hegarty said. "I have three sisters. My sisters and I had a lot of fun growing up. •ere is no doubt that interacting with them shaped my life. We spent a lot of time together, at least until we were old enough to drive. We still get together for holidays and other special events, along with our parents, who are doing well." Hegarty's oldest sister went on to become a lawyer until she decided to retire from that business and open an antiques shop with her husband, also a former lawyer. Hegarty's next oldest sister, as it happens, is the accom- plished New York City artist Valerie Hegarty, and his younger sister holds degrees in biology and is doing some great environmental work, he said. While his work has placed great demands on Hegarty in terms of time and energy, he pointed out, "Engineer- ing has also been a rewarding career path that has enabled me and my fam- ily to pursue and enjoy a lot of other interests. For example, my parents owned a cabin on a lake in Maine for decades and Patti and I were able to buy it from them a few years ago. We enjoy a lot of water activities, hiking, biking, and family time there." And just to round out the picture, we note that Hegarty is an avid woodworker, who has made, among other things, a desk for his step-daughter, a custom lo¨ bed for his son, and other items around the house, like a TV stand and a wet bar for the basement. Here, he said, his engineering background has come in handy: "I have used a fair amount of trigonometry for dimensioning the pieces for various projects! And I also like to read and I still play guitar, and work on the house." Ever the multi- tasker. Whatever else we know about Christopher Hegarty – all work, all play, all-American – he is no dull boy. Chris Hegarty hiking in Svalbard. HUMAN ENGINEERING
