In 1843, Taylor decided to change her focus on compasses in iron ships. She worked specifically with the astronomer George Biddell Airy, who later would recommend her name to anyone who would be able to utilize her efforts. In 1845, she appointed William Reynolds to develop a nautical instrument factory in her name, resulting in instruments being entered in the Great Exhibition 1851 and the International Exhibition of 1862. A series of unfortunate events fell upon her, first starting with her husband George Taylor' death in 1853, and then both of her senior employees leaving her to start their businesses. From 1860, Taylor began to receive a Civil List Pension of £50 per year, and around this year her nautical academy changed its name to Mrs Janet Taylor and Co, meaning that it had turned into a company. There is record of her paying land tax for her company up until 1866 but by 1870 she became ill. During this time she was with her sister Joyce and her husband the Rev. Matthew Chester. On the 26th of January in 1870, Mrs. Janet Taylor died of bronchitis. On her death certificate, her occupation is stated as "Teacher of Navigation."
