Ionospheric irregularity studies are important aspects for understandingionospheric physics and related processes, especially near the low-latituderegions. However, simultaneous measurements (utilizing the L-band signals ofNavIC and GPS) of irregularity scale sizes over the Indian longitude sector,has not been addressed extensively. To address this problem, the paper presentssimultaneous characterization of low-latitude ionospheric irregularities over alocation near the northern EIA crest (Indore: 22.52$^\circ$N, 75.92$^\circ$Egeographic and magnetic dip of 32.23$^\circ$N) and a location (Hyderabad:17.41$^\circ$N, 78.55$^\circ$E geographic and magnetic dip of 21.69$^\circ$N)between the crest and the magnetic equator, utilizing the Indian navigationsystem, NavIC and GPS L5 signal C/N$_o$ variations to determine the range ofthe ionospheric irregularity scale sizes using Power Spectral Density (PSD)analysis. The study period spans from September 2017- September 2019, coveringboth disturbed and quiet-time conditions in the declining phase of solar cycle24. Observations show that the irregularity scale size ranges from about 500 mto 6 km. This study for the first time, shows the nature of the temporal PSDfor ionospheric scintillation during varying solar and geophysical conditions,by measuring the irregularity scale sizes utilizing simultaneous observationsfrom NavIC and GPS from locations near the northern crest of the EIA and inbetween crest and the magnetic equator, ensuring proper characterization ofionosphere over the geosensitive Indian subcontinent.
