Vikramaditya mentioned in Ancient Vedic Astrology Books

Jyotirvidabharana is an astrological work by Kalidasa.

Here, he mentions that he was writing it to enhance the fame of Vikramaditya of the Paramara dynasty (Panwar dynasty), his patron king. [Jyotirvidabharana. Sloka No. 4—89]
Kalidasa also defines the word Saka.
He says that whoever kills large number of Sakas, will become Saka-Karaka.
This book Jyotirvidabharana, says Kalidasa, he began to write in the month Vaisakha (around May) of 3068 Kali Era (or 33 BCE) and was completed in the month Kartika (around november) of the same year.
In the beginning of the 22nd chapter Kalidasa described, to some extent, the Emperor Vikramaditya and in the 6th sloka he says that this book of 22 chapters and 1474 slokas is written with the purpose of invoking good to Vikramaditya, the Emperor of Bharat.
In the 7th sloka of Chapter 22 Kalidasa gives some particulars of Vikrama’s empire, which are as follows:-
1. It extended over the whole of Bharata-Varsha of 180 Big jyotisha yojanas (approximately 1800 miles)in length and breadth. ( 1 Big yojana [not to be confused with Yojana in Ramayana etc] in those days is close to 10 miles )
2. The Bharata-Varsha shines forth with the culture of the Vedas and Dharma Sastras. This book is dedicated for the good of Vikramaditya, the emporer of Malwa, by me (Kalidasa).

In the 8th and 9th slokas of Chapter 22 Kalidasa gives a list of poets and pundits adorning the court of Vikrama.
